Attributes[<Interface>]

The NodeEventTarget is a Node.js-specific extension to EventTarget that emulates a subset of the EventEmitter API.

@since v14.5.0

Methods

static member Create (addListener: Func<string,(obj -> unit),NodeEventTarget>, emit: Func<string,obj,bool>, eventNames: unit -> string array, listenerCount: string -> float, setMaxListeners: float -> unit, getMaxListeners: unit -> float, off: Func<string,(obj -> unit),EventListenerOptions option,NodeEventTarget>, on: Func<string,(obj -> unit),NodeEventTarget>, once: Func<string,(obj -> unit),NodeEventTarget>, removeAllListeners: string option -> NodeEventTarget, removeListener: Func<string,(obj -> unit),EventListenerOptions option,NodeEventTarget>, addEventListener: Action<string,U2<(Event2 -> unit),EventListenerObject>,U2<bool,AddEventListenerOptions> option>, dispatchEvent: Event2 -> bool, removeEventListener: Action<string,U2<(Event2 -> unit),EventListenerObject>,U2<bool,EventListenerOptions2> option>) : NodeEventTarget
abstract member addListener (type: string, listener: obj -> unit) : NodeEventTarget

Node.js-specific extension to the EventTarget class that emulates the equivalent EventEmitter API. The only difference between addListener() and addEventListener() is that addListener() will return a reference to the EventTarget.

@since v14.5.0

abstract member emit (type: string, arg: obj) : bool

Node.js-specific extension to the EventTarget class that dispatches the arg to the list of handlers for type.

@since v15.2.0

Returns. true if event listeners registered for the type exist, otherwise false.

abstract member eventNames () : string array

Node.js-specific extension to the EventTarget class that returns an array of event type names for which event listeners are registered.

@since 14.5.0

abstract member getMaxListeners () : float

Node.js-specific extension to the EventTarget class that returns the number of max event listeners.

@since v14.5.0

abstract member listenerCount (type: string) : float

Node.js-specific extension to the EventTarget class that returns the number of event listeners registered for the type.

@since v14.5.0

abstract member off (type: string, listener: obj -> unit, ?options: EventListenerOptions) : NodeEventTarget

Node.js-specific alias for eventTarget.removeEventListener().

@since v14.5.0

abstract member on (type: string, listener: obj -> unit) : NodeEventTarget

Node.js-specific alias for eventTarget.addEventListener().

@since v14.5.0

abstract member once (type: string, listener: obj -> unit) : NodeEventTarget

Node.js-specific extension to the EventTarget class that adds a once listener for the given event type. This is equivalent to calling on with the once option set to true.

@since v14.5.0

abstract member removeAllListeners (?type: string) : NodeEventTarget

Node.js-specific extension to the EventTarget class. If type is specified, removes all registered listeners for type, otherwise removes all registered listeners.

@since v14.5.0

abstract member removeListener (type: string, listener: obj -> unit, ?options: EventListenerOptions) : NodeEventTarget

Node.js-specific extension to the EventTarget class that removes the listener for the given type. The only difference between removeListener() and removeEventListener() is that removeListener() will return a reference to the EventTarget.

@since v14.5.0

abstract member setMaxListeners (n: float) : unit

Node.js-specific extension to the EventTarget class that sets the number of max event listeners as n.
