▸ hasEventListener(type, callback?): boolean
Check if a list of event listeners for this type contains this listener
| Name | Type | Description |
|---|---|---|
type | string | type of event or property |
Optional callback | Function | to be called, if null, check if any callback is registered |
boolean
▸ Protected initLoader(loader?): CompositeSource
Initializes the loader provided
| Name | Type | Description |
|---|---|---|
Optional loader | AbstractLoader | loader to use |
this
▸ isDataLoaded(): boolean
Returns true if server data is already loaded (or no loader provided)
boolean
▸ isDataReady(): boolean
Checks if source (current visible) data is loaded and ready to be rendered
boolean
▸ isDisposed(): boolean
Returns whether this object has been disposed
boolean
▸ isLoading(): boolean

▸ notify<E>(type, source, args?): CompositeSource
Notify listeners
| Name | Type |
|---|---|
E | extends string |
| Name | Type | Description |
|---|---|---|
type | E | event types |
source | Vector | of the event |
Optional args | EventMap[E] | arguments of the event |
this
▸ off<E>(type?, callback?): CompositeSource
Detach listener on event. Calling .off() with no arguments removes all attached listeners. Calling .off(type) with no callback removes all attached listeners for specific type.
| Name | Type |
|---|---|
E | extends string |
| Name | Type | Description |
|---|---|---|
Optional type | E | type of the event |
Optional callback | (eventType: E, sender: CompositeSource, args: EventMap[E]) => void | function to be called |
this
▸ on<E>(type, callback): CompositeSource
Attach listener on event that will be called whenever the specified event is delivered to the target
If the callback function is already in the list of event listeners for this target, the function is not added a second time.
If a particular anonymous function is in the list of event listeners registered for a certain target, and then later in the code, an identical anonymous function is given in an "on" call, the second function will also be added to the list of event listeners for that target.
