eZ.NotificationList Class

The Notification Model List

Constructor

Methods

_add

(
  • model
  • [options]
)
Model protected
Adds the specified _model_ if it isn't already in this list. If the model's clientId or id matches that of a model that's already in the list, an error event will be fired and the model will not be added.

Parameters:

  • model Model | Object
    Model or object to add.
  • [options] Object optional
    Data to be mixed into the event facade of the add event for the added model.
    • [silent=false] Boolean optional

      If true, no add event will be fired.

Returns:

Model: The added model.

_addAttrs

(
  • cfgs
  • values
  • lazy
)
private
Implementation behind the public addAttrs method. This method is invoked directly by get if it encounters a scenario in which an attribute's valueFn attempts to obtain the value an attribute in the same group of attributes, which has not yet been added (on demand initialization).

Parameters:

  • cfgs Object
    An object with attribute name/configuration pairs.
  • values Object
    An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.
  • lazy Boolean
    Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.

_addLazyAttr

(
  • name
  • [lazyCfg]
)
private
Finishes initializing an attribute which has been lazily added.

Parameters:

  • name Object
    The name of the attribute
  • [lazyCfg] Object optional
    Optional config hash for the attribute. This is added for performance along the critical path, where the calling method has already obtained lazy config from state.

_addOutOfOrder

(
  • name
  • cfg
)
private
Utility method used by get/set to add attributes encountered out of order when calling addAttrs(). For example, if: this.addAttrs({ foo: { setter: function() { // make sure this bar is available when foo is added this.get("bar"); } }, bar: { value: ... } });

Parameters:

  • name String
    attribute name
  • cfg Object
    attribute configuration

_afterIdChange

(
  • e
)
protected
Updates the model maps when a model's id attribute changes.

Parameters:

_aggregateAttrs

(
  • allAttrs
)
Object private
A helper method, used by _initHierarchyData to aggregate attribute configuration across the instances class hierarchy. The method will protect the attribute configuration value to protect the statically defined default value in ATTRS if required (if the value is an object literal, array or the attribute configuration has cloneDefaultValue set to shallow or deep).

Parameters:

  • allAttrs Array
    An array of ATTRS definitions across classes in the hierarchy (subclass first, Base last)

Returns:

Object: The aggregate set of ATTRS definitions for the instance

_attachList

(
  • model
)
protected
Adds this list as a bubble target for the specified model's events.

Parameters:

  • model Model
    Model to attach to this list.

_attrCfgHash

() private
Utility method to define the attribute hash used to filter/whitelist property mixes for this class for iteration performance reasons.

_baseDestroy

() private
Internal destroy implementation for BaseCore

_baseInit

() private
Internal initialization implementation for BaseCore

_clear

() protected
Clears all internal state and the internal list of models, returning this list to an empty state. Automatically detaches all models in the list.

_cloneDefaultValue

(
  • cfg
)
private
This method assumes that the value has already been checked to be an object. Since it's on a critical path, we don't want to re-do the check.

Parameters:

  • cfg Object

_compare

(
  • a
  • b
)
Number protected

Inherited from ModelList: app/js/model-list.js:997

Available since 3.5.0

Compares the value _a_ to the value _b_ for sorting purposes. Values are assumed to be the result of calling a model's comparator() method. You can override this method to implement custom sorting logic, such as a descending sort or multi-field sorting.

Parameters:

  • a Mixed
    First value to compare.
  • b Mixed
    Second value to compare.

Returns:

Number: -1 if _a_ should come before _b_, 0 if they're equivalent, 1 if _a_ should come after _b_.

(
  • allAttrs
  • userVals
)
Object private

)
String private
Returns the fully qualified type, given a short type string. That is, returns "foo:bar" when given "bar" if "foo" is the configured prefix. NOTE: This method, unlike _getType, does no checking of the value passed in, and is designed to be used with the low level _publish() method, for critical path implementations which need to fast-track publish for performance reasons.

list.add(otherList);

addAttr

(
  • name
  • config
  • lazy
)
Object chainable

Adds an attribute with the provided configuration to the host object.

The config argument object supports the following properties:

value <Any>
The initial value to set on the attribute
valueFn <Function | String>

A function, which will return the initial value to set on the attribute. This is useful for cases where the attribute configuration is defined statically, but needs to reference the host instance ("this") to obtain an initial value. If both the value and valueFn properties are defined, the value returned by the valueFn has precedence over the value property, unless it returns undefined, in which case the value property is used.

valueFn can also be set to a string, representing the name of the instance method to be used to retrieve the value.

readOnly <boolean>
Whether or not the attribute is read only. Attributes having readOnly set to true cannot be modified by invoking the set method.
writeOnce <boolean> or <string>
Whether or not the attribute is "write once". Attributes having writeOnce set to true, can only have their values set once, be it through the default configuration, constructor configuration arguments, or by invoking set.

The writeOnce attribute can also be set to the string "initOnly", in which case the attribute can only be set during initialization (when used with Base, this means it can only be set during construction)

setter <Function | String>

The setter function used to massage or normalize the value passed to the set method for the attribute. The value returned by the setter will be the final stored value. Returning Attribute.INVALID_VALUE, from the setter will prevent the value from being stored.

setter can also be set to a string, representing the name of the instance method to be used as the setter function.

getter <Function | String>

The getter function used to massage or normalize the value returned by the get method for the attribute. The value returned by the getter function is the value which will be returned to the user when they invoke get.

getter can also be set to a string, representing the name of the instance method to be used as the getter function.

validator <Function | String>

The validator function invoked prior to setting the stored value. Returning false from the validator function will prevent the value from being stored.

validator can also be set to a string, representing the name of the instance method to be used as the validator function.

lazyAdd <boolean>
Whether or not to delay initialization of the attribute until the first call to get/set it. This flag can be used to over-ride lazy initialization on a per attribute basis, when adding multiple attributes through the addAttrs method.

The setter, getter and validator are invoked with the value and name passed in as the first and second arguments, and with the context ("this") set to the host object.

Configuration properties outside of the list mentioned above are considered private properties used internally by attribute, and are not intended for public use.

Parameters:

  • name String

    The name of the attribute.

  • config Object

    An object with attribute configuration property/value pairs, specifying the configuration for the attribute.

    NOTE: The configuration object is modified when adding an attribute, so if you need to protect the original values, you will need to merge the object.

  • lazy Boolean

    (optional) Whether or not to add this attribute lazily (on the first call to get/set).

Returns:

Object:

A reference to the host object.

addAttrs

(
  • cfgs
  • values
  • lazy
)
Object chainable
Configures a group of attributes, and sets initial values.

NOTE: This method does not isolate the configuration object by merging/cloning. The caller is responsible for merging/cloning the configuration object if required.

Parameters:

  • cfgs Object
    An object with attribute name/configuration pairs.
  • values Object
    An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.
  • lazy Boolean
    Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.

Returns:

Object: A reference to the host object.

addTarget

(
  • o
)
chainable
Registers another EventTarget as a bubble target. Bubble order is determined by the order registered. Multiple targets can be specified. Events can only bubble if emitFacade is true. Included in the event-custom-complex submodule.

Parameters:

after

(
  • type
  • fn
  • [context]
  • [arg*]
)
EventHandle
Subscribe to a custom event hosted by this object. The supplied callback will execute after any listeners add via the subscribe method, and after the default function, if configured for the event, has executed.

Parameters:

  • type String
    The name of the event
  • fn Function
    The callback to execute in response to the event
  • [context] Object optional
    Override this object in callback
  • [arg*] Any optional
    0..n additional arguments to supply to the subscriber

Returns:

EventHandle: A subscription handle capable of detaching the subscription

attrAdded

(
  • name
)
Boolean
Checks if the given attribute has been added to the host

Parameters:

  • name String
    The name of the attribute to check.

Returns:

Boolean: true if an attribute with the given name has been added, false if it hasn't. This method will return true for lazily added attributes.

before

()
Executes the callback before a DOM event, custom event or method. If the first argument is a function, it is assumed the target is a method. For DOM and custom events, this is an alias for Y.on. For DOM and custom events: type, callback, context, 0-n arguments For methods: callback, object (method host), methodName, context, 0-n arguments

Returns:

detach handle

bubble

(
  • evt
)
Boolean
Propagate an event. Requires the event-custom-complex module.

Parameters:

Returns:

Boolean: the aggregated return value from Event.Custom.fire

comparator

(
  • model
)
Number | String
Define this method to provide a function that takes a model as a parameter and returns a value by which that model should be sorted relative to other models in this list. By default, no comparator is defined, meaning that models will not be sorted (they'll be stored in the order they're added).

Parameters:

  • model Model
    Model being sorted.

Returns:

Number | String: Value by which the model should be sorted relative to other models in this list.

Example:

var list = new Y.ModelList({model: Y.Model});

list.comparator = function (model) {
    return model.get('id'); // Sort models by id.
};

create

(
  • model
  • [options]
  • [callback]
)
Model
Creates or updates the specified model on the server, then adds it to this list if the server indicates success.

Parameters:

  • model Model | Object
    Model to create. May be an existing model instance or a hash of model attributes, in which case a new model instance will be created from the hash.
  • [options] Object optional

  • type
  • fn
  • context
)
EventTarget
Detach one or more listeners the from the specified event

Parameters:

  • type String | Object
    Either the handle to the subscriber or the type of event. If the type is not specified, it will attempt to remove the listener from all hosted events.
  • fn Function
    The subscribed function to unsubscribe, if not supplied, all subscribers will be removed.
  • context Object
    The custom object passed to subscribe. This is optional, but if supplied will be used to disambiguate multiple listeners that are the same (e.g., you subscribe many object using a function that lives on the prototype)

Returns:

detachAll

(
  • type
)
Removes all listeners from the specified event. If the event type is not specified, all listeners from all hosted custom events will be removed.

Parameters:

each

(
  • callback
  • [thisObj]
)
chainable

Inherited from ArrayList but overwritten in app/js/model-list.js:343

Available since 3.6.0

Executes the supplied function on each model in this list. By default, the callback function's this object will refer to the model currently being iterated. Specify a thisObj to override the this object if desired. Note: Iteration is performed on a copy of the internal array of models, so it's safe to delete a model from the list during iteration.

Parameters:

  • callback Function
    Function to execute on each model.
    • model Model

      Model instance.

    • index Number

      Index of the current model.

    • list ModelList

      The ModelList being iterated.

  • [thisObj] Object optional
    Object to use as the this object when executing the callback.

ez-notificationlist

()

Provides the notification model list

filter

(
  • [options]
  • callback
)
Model[] | ModelList

Inherited from ArrayList but overwritten in app/js/model-list.js:375

Available since 3.5.0

Executes the supplied function on each model in this list. Returns an array containing the models for which the supplied function returned a truthy value. The callback function's this object will refer to this ModelList. Use Y.bind() to bind the this object to another object if desired.

Parameters:

  • [options] Object optional
    Filter options.
    • [asList=false] Boolean optional

      If truthy, results will be returned as a new ModelList instance rather than as an array.

  • callback Function
    Function to execute on each model.
    • model Model

      Model instance.

    • index Number

      Index of the current model.

    • list ModelList

      The ModelList being filtered.

Returns:

Model[] | ModelList: Array of models for which the callback function returned a truthy value (empty if it never returned a truthy value). If the options.asList option is truthy, a new ModelList instance will be returned instead of an array.

Example:

// Get an array containing only the models whose "enabled" attribute is
// truthy.
var filtered = list.filter(function (model) {
    return model.get('enabled');
});

// Get a new ModelList containing only the models whose "enabled"
// attribute is truthy.
var filteredList = list.filter({asList: true}, function (model) {
    return model.get('enabled');
});

fire

(
  • type
  • arguments
)
Boolean
Fire a custom event by name. The callback functions will be executed from the context specified when the event was created, and with the following parameters. The first argument is the event type, and any additional arguments are passed to the listeners as parameters. If the first of these is an object literal, and the event is configured to emit an event facade, that object is mixed into the event facade and the facade is provided in place of the original object. If the custom event object hasn't been created, then the event hasn't been published and it has no subscribers. For performance sake, we immediate exit in this case. This means the event won't bubble, so if the intention is that a bubble target be notified, the event must be published on this object first.

Parameters:

  • type String | Object
    The type of the event, or an object that contains a 'type' property.
  • arguments Object
    an arbitrary set of parameters to pass to the handler. If the first of these is an object literal and the event is configured to emit an event facade, the event facade will replace that parameter after the properties the object literal contains are copied to the event facade.

Returns:

Boolean: True if the whole lifecycle of the event went through, false if at any point the event propagation was halted.

modifyAttr

(
  • name
  • config
)
Updates the configuration of an attribute which has already been added.

The properties which can be modified through this interface are limited to the following subset of attributes, which can be safely modified after a value has already been set on the attribute:

readOnly;
writeOnce;
broadcast; and
getter.

Note: New attributes cannot be added using this interface. New attributes must be added using {{#crossLink "AttributeCore/addAttr:method"}}addAttr{{/crossLink}}, or an appropriate manner for a class which utilises Attributes (e.g. the {{#crossLink "Base/ATTRS:property"}}ATTRS{{/crossLink}} property in {{#crossLink "Base"}}Base{{/crossLink}}).

Parameters:

  • name String
    The name of the attribute whose configuration is to be updated.
  • config Object
    An object with configuration property/value pairs, specifying the configuration properties to modify.

on

(
  • type
  • fn
  • [context]
  • [arg*]
)
EventHandle
Subscribe a callback function to a custom event fired by this object or from an object that bubbles its events to this object. this.on("change", this._onChange, this); Callback functions for events published with emitFacade = true will receive an EventFacade as the first argument (typically named "e"). These callbacks can then call e.preventDefault() to disable the behavior published to that event's defaultFn. See the EventFacade API for all available properties and methods. Subscribers to non-emitFacade events will receive the arguments passed to fire() after the event name. To subscribe to multiple events at once, pass an object as the first argument, where the key:value pairs correspond to the eventName:callback. this.on({ "attrChange" : this._onAttrChange, "change" : this._onChange }); You can also pass an array of event names as the first argument to subscribe to all listed events with the same callback. this.on([ "change", "attrChange" ], this._onChange); Returning false from a callback is supported as an alternative to calling e.preventDefault(); e.stopPropagation();. However, it is recommended to use the event methods whenever possible.

Parameters:

  • type String
    The name of the event
  • fn Function
    The callback to execute in response to the event
  • [context] Object optional
    Override this object in callback
  • [arg*] Any optional
    0..n additional arguments to supply to the subscriber

Returns:

EventHandle: A subscription handle capable of detaching that subscription

once

(
  • type
  • fn
  • [context]
  • [arg*]
)
EventHandle
Listen to a custom event hosted by this object one time. This is the equivalent to on except the listener is immediatelly detached when it is executed.

Parameters:

  • type String
    The name of the event
  • fn Function
    The callback to execute in response to the event
  • [context] Object optional
    Override this object in callback
  • [arg*] Any optional
    0..n additional arguments to supply to the subscriber

Returns:

EventHandle: A subscription handle capable of detaching the subscription

onceAfter

(
  • type
  • fn
  • [context]
  • [arg*]
)
EventHandle
Listen to a custom event hosted by this object one time. This is the equivalent to after except the listener is immediatelly detached when it is executed.

Parameters:

  • type String
    The name of the event
  • fn Function
    The callback to execute in response to the event
  • [context] Object optional
    Override this object in callback

    0..n additional arguments to supply to the subscriber

Returns:

EventHandle: A subscription handle capable of detaching that subscription

parse

(
  • response
)
Object
Called to parse the _response_ when the list is loaded from the server. This method receives a server _response_ and is expected to return an array of model attribute hashes. The default implementation assumes that _response_ is either an array of attribute hashes or a JSON string that can be parsed into an array of attribute hashes. If _response_ is a JSON string and either Y.JSON or the native JSON object are available, it will be parsed automatically. If a parse error occurs, an error event will be fired and the model will not be updated. You may override this method to implement custom parsing logic if necessary.

Parameters:

  • response Any
    Server response.

Returns:

Object: Array of model attribute hashes.

parseType

some

(
  • callback
  • [thisObj]
)
Boolean

Inherited from ArrayList but overwritten in app/js/model-list.js:770

Available since 3.6.0

Executes the supplied function on each model in this list, and stops iterating if the callback returns true. By default, the callback function's this object will refer to the model currently being iterated. Specify a thisObj to override the this object if desired. Note: Iteration is performed on a copy of the internal array of models, so it's safe to delete a model from the list during iteration.

Parameters:

  • callback Function
    Function to execute on each model.
    • model Model

      Model instance.

    • index Number

      Index of the current model.

    • list ModelList

Returns:

Boolean: true if the callback returned true for any item, false otherwise.

sort

(
  • [options]
)
chainable
Forcibly re-sorts the list. Usually it shouldn't be necessary to call this method since the list maintains its sort order when items are added and removed, but if you change the comparator function after items are already in the list, you'll need to re-sort.

Parameters:

  • [options] Object optional
    Data to be mixed into the event facade of the reset event.
    • [silent=false] Boolean optional

      If true, no reset event will be fired.

Inherited from EventTarget: event-custom/js/event-target.js:346

Deprecated: use on

subscribe to an event

sync

(
  • action
  • [options]
  • [callback]
)
Override this method to provide a custom persistence implementation for this list. The default method just calls the callback without actually doing anything. This method is called internally by load() and its implementations relies on the callback being called. This effectively means that when a callback is provided, it must be called at some point for the class to operate correctly.

Parameters:

  • action String
    Sync action to perform. May be one of the following: * create: Store a list of newly-created models for the first time. * delete: Delete a list of existing models. * read : Load a list of existing models. * update: Update a list of existing models. Currently, model lists only make use of the read action, but other actions may be used in future versions.
  • [options] Object optional
    Sync options. It's up to the custom sync implementation to determine what options it supports or requires, if any.
  • [callback] Function optional
    Called when the sync operation finishes.
    • err Error

      If an error occurred, this parameter will contain the error. If the sync operation succeeded, err will be falsy.

    • [response] Any optional

      The server's response. This value will be passed to the parse() method, which is expected to parse it and return an array of model attribute hashes.

toArray

() Model[]
Returns an array containing the models in this list.

Returns:

Model[]: Array containing the models in this list.

toJSON

() Object

Inherited from ArrayList but overwritten in app/js/model-list.js:898

Returns an array containing attribute hashes for each model in this list, suitable for being passed to Y.JSON.stringify(). Under the hood, this method calls toJSON() on each model in the list and pushes the results into an array.

Returns:

Object: Array of model attribute hashes.

toString

() String
Default toString implementation. Provides the constructor NAME and the instance guid, if set.

Returns:

String: String representation for this object

Deprecated: use detachAll

Removes all listeners from the specified event. If the event type is not specified, all listeners from all hosted custom events will be removed.

Parameters:

  • type String
    The type, or name of the event

Properties

_allowAdHocAttrs

Boolean protected
This property controls whether or not instances of this class should allow users to add ad-hoc attributes through the constructor configuration hash. AdHoc attributes are attributes which are not defined by the class, and are not handled by the MyClass._NON_ATTRS_CFG

Default: undefined (false)

_isYUIModelList

Boolean protected

Inherited from ModelList: app/js/model-list.js:161

Available since 3.5.0

Total hack to allow us to identify ModelList instances without using instanceof, which won't work when the instance was created in another window or YUI sandbox.

Default: true

model

Model | String
The Model class or subclass of the models in this list. The class specified here will be used to create model instances automatically based on attribute hashes passed to the add(), create(), and reset() methods. You may specify the class as an actual class reference or as a string that resolves to a class reference at runtime (the latter can be useful if the specified class will be loaded lazily).

Default: Y.Model

name

String deprecated

Inherited from BaseCore: base/js/BaseCore.js:297

Deprecated: Use this.constructor.NAME

The string used to identify the class of this object.

Attributes

Boolean readonly
Flag indicating whether or not this object has been through the destroy lifecycle phase.

Default: false

initialized

Boolean readonly
Flag indicating whether or not this object has been through the init lifecycle phase.

Default: false

Events

add

Fired when a model is added to the list. Listen to the on phase of this event to be notified before a model is added to the list. Calling e.preventDefault() during the on phase will prevent the model from being added. Listen to the after phase of this event to be notified after a model has been added to the list.

Event Payload:

  • model Model
    The model being added.
  • index Number
    The index at which the model will be added.

create

Inherited from ModelList: app/js/model-list.js:54

Available since 3.5.0

Fired when a model is created or updated via the create() method, but before the model is actually saved or added to the list. The add event will be fired after the model has been saved and added to the list.

Event Payload:

  • model Model
    The model being created/updated.

destroy

Lifecycle event for the destroy phase, fired prior to destruction. Invoking the preventDefault method on the event object provided to subscribers will prevent destruction from proceeding.

Subscribers to the "after" moment of this event, will be notified after destruction is complete (and as a result cannot prevent destruction).

Event Payload:

error

Fired when an error occurs, such as when an attempt is made to add a duplicate model to the list, or when a sync layer response can't be parsed.

Event Payload:

  • error Any
    Error message, object, or exception generated by the error. Calling toString() on this should result in a meaningful error message.
  • src String
    Source of the error. May be one of the following (or any custom error source defined by a ModelList subclass): * add: Error while adding a model (probably because it's already in the list and can't be added again). The model in question will be provided as the model property on the event facade. * parse: An error parsing a JSON response. The response in question will be provided as the response property on the event facade. * remove: Error while removing a model (probably because it isn't in the list and can't be removed). The model in question will be provided as the model property on the event facade.

init

Lifecycle event for the init phase, fired prior to initialization. Invoking the preventDefault() method on the event object provided to subscribers will prevent initialization from occuring.

Subscribers to the "after" momemt of this event, will be notified after initialization of the object is complete (and therefore cannot prevent initialization).
