## Methods

### `_addAttrs`

(

- `cfgs`
- `values`
- `lazy`

)
private

Inherited from AttributeCore: `attribute/js/AttributeCore.js:836`

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

Inherited from AttributeCore: `attribute/js/AttributeCore.js:382`

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.

### `_aggregateAttrs`

(

- `allAttrs`

)
Object private

Inherited from BaseCore: `base/js/BaseCore.js:575`

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

### `_attrCfgHash`

### `addAttr`

(

- `name`
- `config`
- `lazy`

)
Object chainable

Inherited from AttributeCore: `attribute/js/AttributeCore.js:157`

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

Inherited from AttributeCore: `attribute/js/AttributeCore.js:805`

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.

EventTarget

Inherited from EventTarget: `event-custom/js/event-target.js:695`

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.

EventHandle

Inherited from EventTarget: `event-custom/js/event-target.js:188`

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

## Events

### `destroy`

Inherited from BaseObservable: `base/js/BaseObservable.js:151`

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:

- `e` EventFacade

  Event object

### `init`

Inherited from BaseObservable: `base/js/BaseObservable.js:62`

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.
