Package org.djutils.event

package org.djutils.event
Provides classes and interfaces for asynchronous communication. The event package is designed around four main classes:
  • The EventListener defining callback mechanism for a listener.
  • The EventProducer defining registration capabilities.
  • The Event defining the events which are sent by a producer and received by a listener.
  • The EventType allowing for strongly typed Events
The classes providing a reference implementation of these interfaces are designed for multi-threaded deployment.

  • Class
    Description
    Event
    The Event class forms the reference implementation for the Event.
    EventListener
    The EventListener interface creates a callback method for publishers to inform their clients.
    EventListenerMap
    The EventListenerMap maps EventTypes on lists of References to EventListeners.
    EventProducer
    EventProducer is the interface that exposes a few of the methods of the implementation of an EventProducer to the outside world: the ability to add and remove listeners.
    EventType
    Reference implementation of the EventType.
    LocalEventProducer
    The LocalEventProducer defines the registration and fireEvent operations of an event producer.
    TimedEvent<T extends Comparable<T>>
    The TimedEvent is the reference implementation for a timed event.
