Properties

public addObserver: ModifyObserver

public concatenatedProperties: Array<any>

Defines the properties that will be concatenated from the superclass (instead of overridden).

public events: {}

public static isClass: boolean

public isDestroyed: boolean

Destroyed object property flag. If this property is true the observers and bindings were already removed by the effect of calling the destroy() method.

public isDestroying: boolean

Destruction scheduled flag. The destroy() method has been called. The object stays intact until the end of the run loop at which point the isDestroyed flag is set.

public static isMethod: boolean

Methods

public beginPropertyChanges(): Observable

Returns

Observable

public cacheFor(keyName: string): any

Parameters

  • keyName: string

Returns

any

public decrementProperty(keyName: string, decrement?: number): number

Parameters

  • keyName: string
  • decrement?: number optional

Returns

number

public destroy(): CoreObject

Destroys an object by setting the isDestroyed flag and removing its metadata, which effectively destroys observers and bindings. If you try to set a property on a destroyed object, an exception will be raised. Note that destruction is scheduled for the end of the run loop and does not happen immediately. It will set an isDestroying flag immediately.

Returns

CoreObject
