    open ()

    Inherited from EndPoint: EndPoint.js:35

    Opens this end point and starts listening for events.

    Use this method to keep the end point open even when no event listeners are attached.

    untilOpen () Promise

    Inherited from EndPoint: EndPoint.js:142

    Returns a promise that will be resolved when this end point is opened

    Returns:

    Promise
