import { EventEmitter } from '@netwiv/api/plugins/shell';

Constructor

new EventEmitter<E extends Record<string, any>>()

Instance members

addListener

addListener<N>(eventName: N, listener: (arg: E[N]): void) => EventEmitter<E>

Alias for emitter.on(eventName, listener).

listenerCount

listenerCount<N extends keyof E>(eventName: N): number

Returns the number of listeners listening to the event named eventName.

off

off<N>(eventName: N, listener: (arg: E[N]): void) => EventEmitter<E>

Removes the all specified listener from the listener array for the event eventName Returns a reference to the EventEmitter, so that calls can be chained.

on

on<N>(eventName: N, listener: (arg: E[N]): void) => EventEmitter<E>

Adds the listener function to the end of the listeners array for the event named eventName. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of eventNameand listener will result in the listener being added, and called, multiple times.

Returns a reference to the EventEmitter, so that calls can be chained.

once

once<N>(eventName: N, listener: (arg: E[N]): void) => EventEmitter<E>

Adds a one-timelistener function for the event named eventName. The next time eventName is triggered, this listener is removed and then invoked.

Returns a reference to the EventEmitter, so that calls can be chained.

prependListener

prependListener<N>(eventName: N, listener: (arg: E[N]): void) => EventEmitter<E>

Adds the listener function to the beginning of the listeners array for the event named eventName. No checks are made to see if the listener has already been added. Multiple calls passing the same combination of eventNameand listener will result in the listener being added, and called, multiple times.

Returns a reference to the EventEmitter, so that calls can be chained.

prependOnceListener

prependOnceListener<N>(eventName: N, listener: (arg: E[N]): void) => EventEmitter<E>

Adds a one-timelistener function for the event named eventName to the_beginning_ of the listeners array. The next time eventName is triggered, this listener is removed, and then invoked.

Returns a reference to the EventEmitter, so that calls can be chained.

removeAllListeners

removeAllListeners<N>(event?: N | undefined): EventEmitter<E>

Removes all listeners, or those of the specified eventName.

Returns a reference to the EventEmitter, so that calls can be chained.

removeListener

removeListener<N>(eventName: N, listener: (arg: E[N]): void) => EventEmitter<E>

Alias for emitter.off(eventName, listener).
