Private emitChanged

getMaxListeners

  • Returns the current max listener value for the EventEmitter which is either set by emitter.setMaxListeners(n) or defaults to defaultMaxListeners.

    Returns number

    Since

    v1.0.0

getRepresentation

hasResource

Private isKnownActivity

  • Parameters

    • Optional term: Term

    Returns term is NamedNode<"https://www.w3.org/ns/activitystreams#Create"> | NamedNode<"https://www.w3.org/ns/activitystreams#Add"> | NamedNode<"https://www.w3.org/ns/activitystreams#Delete"> | NamedNode<"https://www.w3.org/ns/activitystreams#Remove"> | NamedNode<"https://www.w3.org/ns/activitystreams#Update">

modifyResource

setMaxListeners

  • By default EventEmitters will print a warning if more than 10 listeners are added for a particular event. This is a useful default that helps finding memory leaks. The emitter.setMaxListeners() method allows the limit to be modified for this specific EventEmitter instance. The value can be set toInfinity (or 0) to indicate an unlimited number of listeners.

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

    Parameters

    • n: number

    Returns MonitoringStore<T>

    Since

    v0.3.5
