    Methods

    _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
    )
    private

    Finishes initializing an attribute which has been lazily added.

    Parameters:

    • name Object

      The name of the attribute

    _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

    )
    Object private

    Parameters:

    • allAttrs Object

      The user configuration object

    _protectAttrs

    (
    • attrs
    )
    Object deprecated protected

    Inherited from AttributeCore: attribute/js/AttributeCore.js:815

    Utility method to protect an attribute configuration hash, by merging the entire object and the individual attr config objects.

    Parameters:

    • attrs Object

      A hash of attribute to configuration object pairs.

    Returns:

      The name of the attribute.

    • value Any

      The value to set the attribute to.

    • opts Object

      (Optional) Optional event data to be mixed into the event facade passed to subscribers of the attribute's change event. This is currently a hack. There's no real need for the AttributeCore implementation to support this parameter, but breaking it out into AttributeObservable, results in additional function hops for the critical path.

    Sets the stored value for the attribute, in either the internal state object, or the state proxy if it exits

    Parameters:

    • name String

      The name of the attribute

    • value Any

      The value of the attribute

    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
    )

    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.

    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.

    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.

    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.

    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:

    EventTarget: the event host

    get

    (
    • name
    )
    Any

    Returns the current value of the attribute. If the attribute has been configured with a 'getter' function, this method will delegate to the 'getter' to obtain the value of the attribute.

    Parameters:

    • name String

      The name of the attribute. If the value of the attribute is an Object, dot notation can be used to obtain the value of a property of the object (e.g. get("x.y.z"))

    Returns:

    Any: The value of the attribute

    getAttrs

    (
    • attrs
    )
    Object

    Gets multiple attribute values.

    Parameters:

    • attrs Array | boolean

      Optional. An array of attribute names. If omitted, all attribute values are returned. If set to true, all attributes modified from their initial values are returned.

    Returns:

    Object: An object with attribute name/value pairs.

    getEvent

    (
    • type
    • prefixed

    CustomEvent

    Returns the custom event of the provided type has been created, a falsy value otherwise

    Parameters:

    • type String

      the type, or name of the event

    )
    BaseCore chainable

    Inherited from BaseObservable but overwritten in base/js/BaseCore.js:219

    Init lifecycle method, invoked during construction. Sets up attributes and invokes initializers for the class hierarchy.

    Parameters:

    • cfg Object

      Object with configuration property name/value pairs

    Returns:

    BaseCore: A reference to this object

    initializer

    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.

    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.

    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, or pass an array of event names as the first argument to subscribe to all listed events with the same callback.

    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

    Events

    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:

    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).

    Event Payload:

    • e EventFacade

      Event object, with a cfg property which refers to the configuration object passed to the constructor.
