public many(event: string, timesToListen: number, listener: Function): EventModule

Adds a listener that will execute n times for the event before being removed. The listener is invoked only the first time the event is fired, after which it is removed.

Parameters

• event: string

• timesToListen: number

• listener: Function

Returns

EventModule

public off(event: string, listener: Function): EventModule

Parameters

• event: string

EventModule

public offAny(listener: Function): EventModule

Removes the listener that will be fired when any event is emitted.

Parameters

• listener: Function

Returns

EventModule

public on(event: string, listener: Function): EventModule

Parameters

• event: string

• listener: Function

Returns

EventModule

public onAny(listener: Function): EventModule

Adds a listener that will be fired when any event is emitted.

Parameters

• listener: Function

Returns

EventModule

public once(event: string, listener: Function): EventModule

Adds a one time listener for the event. The listener is invoked only the first time the event is fired, after which it is removed.

Parameters

• event: string

• listener: Function

Returns

EventModule

public removeAllListeners(event: string): EventModule

Removes all listeners, or those of the specified event.

Parameters

• event: string

Returns

EventModule

public removeListener(event: string, listener: Function): EventModule

Remove a listener from the listener array for the specified event. Caution: changes array indices in the listener array behind the listener.

Parameters

• event: string

• listener: Function

Returns

EventModule

public setMaxListener(n: number)

By default EventEmitters will print a warning if more than 10 listeners are added to it. This is a useful default which helps finding memory leaks. Obviously not all Emitters should be limited to 10. This function allows that to be increased.

Set to zero for unlimited.

Parameters

• n: number
