Class EventListenerTree

constructor

• new EventListenerTree(parent?, segment?): EventListenerTree

• Parameters

  • Optional parent: any
  • Optional segment: string

  Returns EventListenerTree

children

listeners

Optional parent

Optional segment

addListener

• addListener(segments, listener): this

• Add a listener to a path location. Listener should be unique per path location, and calling twice with the same segments and listener value has no effect. Unlike EventEmitter, listener may be any type of value

  Parameters

  • segments: Segments
  • listener: any

  Returns this

destroy

• destroy(): void

• Remove the reference to this node from its parent so that it can be garbage collected. This is called internally when all listeners to a node are removed

  Returns void

getAffectedListeners

• getAffectedListeners(segments): any[]

• Return an array with each of the listeners that may be affected by a change to segments. These are:

  1. Listeners to each node from the root to the node for segments
  2. Listeners to all descendent nodes under segments

  Parameters

  • segments: Segments

  Returns any[]

  listeners

getDescendantListeners

• getDescendantListeners(segments): any[]

• Return an array with each of the listeners to descendent nodes, not including listeners to segments itself

  Parameters

  • segments: Segments

  Returns any[]

  listeners

getListeners

• getListeners(segments): any

• Return direct listeners to segments

  Parameters

  • segments: Segments

  Returns any

  listeners

getOwnDescendantListeners

• getOwnDescendantListeners(): any[]

• Return an array with each of the listeners to descendent nodes, not including listeners to this node itself

  Returns any[]

  listeners

getWildcardListeners

• getWildcardListeners(segments): any[]

• Return an array with each of the listeners to segments, including treating wildcard segments ('*') and remainder segments ('**') as matches

  Parameters

  • segments: Segments

  Returns any[]

  listeners

removeAllListeners

• removeAllListeners(segments): void

• Remove all listeners and descendent listeners for a path location

  Parameters

  • segments: Segments

  Returns void

removeListener

• removeListener(segments, listener): void

• Remove a listener from a path location

  Parameters

  • segments: Segments
  • listener: any

  Returns void

removeOwnListener

• removeOwnListener(listener): void

• Remove a listener from the current node

  Parameters

  • listener: any

  Returns void
