new DispatcherImpl()
Initializes the dispatcher.
dispatcherImpl._eventListeners : Map.<string, Map.<function(\*), Set.<?Object>>>
Map of event names to a map of event listeners to a set of scopes to which the event listener should be bound when being executed due to the event.
Kind: instance property of DispatcherImpl
dispatcherImpl.clear()
Kind: instance method of DispatcherImpl
dispatcherImpl.listen()
Kind: instance method of DispatcherImpl
dispatcherImpl.unlisten()
Kind: instance method of DispatcherImpl

dispatcherImpl._createNewEvent(event)
Create new Map storage of listeners for the specified event.
Kind: instance method of DispatcherImpl
| Param | Type | Description |
|---|---|---|
| event | string |
The name of the event. |
dispatcherImpl._createNewListener(event, listener)
Create new Set storage of scopes for the specified event and listener.
Kind: instance method of DispatcherImpl
| Param | Type | Description |
|---|---|---|
| event | string |
The name of the event. |
| listener | function |
The event listener. |
dispatcherImpl._getScopesOf(event, listener) ⇒ Set.<?Object>
Retrieves the scopes in which the specified event listener should be executed for the specified event.
Kind: instance method of DispatcherImpl
Returns: Set.<?Object> - The scopes in which the specified listeners
should be executed in case of the specified event. The returned
set is an unmodifiable empty set if no listeners are registered
for the event.
| Param | Type | Description |
|---|---|---|
| event | string |
The name of the event. |
| listener | function |
The event listener. |
dispatcherImpl._getListenersOf(event) ⇒ Map.<function(\*), Set.<?Object>>
Retrieves the map of event listeners to scopes they are bound to.
Kind: instance method of DispatcherImpl
Returns: Map.<function(\*), Set.<?Object>> - A map of event listeners to the
scopes in which they should be executed. The returned map is an
unmodifiable empty map if no listeners are registered for the
event.
| Param | Type | Description |
|---|---|---|
| event | string |
The name of the event. |
EMPTY_MAP : Map.<function(\*), Set.<?Object>>

the _eventListeners map.
Kind: global constant
EMPTY_SET : Set.<?Object>
An empty immutable set of event listener scopes, used for a mismatch in the
_eventListeners map.
