removeAllListeners

• removeAllListeners<Type extends keyof NamespaceEvents>(type?: Type): this

  Type Parameters

  • Type extends keyof NamespaceEvents

  Parameters

  • Optionaltype: Type

  Returns this

  Description

  removes all listeners, or those of the specified event.

removeListener

  Type Parameters

  • Type extends keyof NamespaceEvents
  • Callback extends
        | ((sparkline: Sparkline) => void)
        | ((sparkline: Sparkline) => void)

        | ((controller: Controller) => void)

  Parameters

  • type: Type
  • listener: Callback

  Returns this

  Description

  remove a listener from the listener array for the specified event.

setMaxListeners

• setMaxListeners(maxListeners: number): this

  Parameters

  • maxListeners: number

  Returns this

  Description

  by default EventEmitters will print a warning if more than 10 listeners are added for a particular event. This is a useful default which helps finding memory leaks. Obviously not all Emitters should be limited to 10. This function allows that limit to be increased. Set to zero for unlimited.

Staticguard

• guard(cb: GuardCb): void

  Parameters

  • cb: GuardCb

  Returns void

  Description

  set custom error handler for event listeners

StaticlistenerCount

• listenerCount<EvType extends Events, Type extends string>(
      emitter: chartbreaker.EventEmitter<EvType>,
      type: Type,
  ): number

  Type Parameters

  • EvType extends Events
  • Type extends string

  Parameters

  • emitter: chartbreaker.EventEmitter<EvType>
  • type: Type

  Returns number

  Description

  returns number of listeners on specified emitter for specified type

StaticsetDefaultMaxListeners

• setDefaultMaxListeners(maxListeners: number): void

  Parameters

  • maxListeners: number

  Returns void

  Description

  set default amount for limit warning
