public class Event extends EventObject

The base class for all events generated by this library.

The events produced by objects in this library are arranged in an inheritance hierarchy. This base class defines some basic properties common to all configuration events. Especially, an event has an EventType which describes its semantics. The event type can also be used for filtering for events or for defining event listeners on a fine-grained basis.

  • Field Details

    • ANY

      public static final EventType<Event> ANY
      The root event type for all configuration-related events. All specific event types have this type as super direct (directly or indirectly).
  • Constructor Details

    • Event

      public Event(Object source, EventType<? extends Event> evType)
      Creates a new instance of Event and sets basic properties.
      source - the object on which the Event initially occurred (must not be null)
      evType - the type of this event (must not be null)
      IllegalArgumentException - if a required parameter is null

    • appendPropertyRepresentation

      protected void appendPropertyRepresentation(StringBuilder buf, String property, Object value)
      Helper method for appending a representation for a property to the overall string representation for this object. This method is called by toString() for generating string fragments for the properties of this class. It can also be used by derived classes which extend the string representation of this base class.
      buf - the target buffer
      property - the name of the property
      value - the property value
    • getEventType

      public EventType<? extends Event> getEventType()
      Gets the type of this event.
      the event type
    • toString

      public String toString()
      Returns a string representation for this object. This string contains the event class and a list of all properties.
      toString in class EventObject
      a string for this object
