Class EventImpl

  • All Implemented Interfaces:
    Event
    Direct Known Subclasses:
    MutationEventImpl, UIEventImpl
    public class EventImpl
extends Object
implements Event
    EventImpl is an implementation of the basic "generic" DOM Level 2 Event object. It may be subclassed by more specialized event sets. Note that in our implementation, events are re-dispatchable (dispatch clears the stopPropagation and preventDefault flags before it starts); I believe that is the DOM's intent but I don't see an explicit statement to this effect.

      • initEvent

        public void initEvent​(String eventTypeArg,
                      boolean canBubbleArg,
                      boolean cancelableArg)
        The DOM doesn't deal with constructors, so instead we have an initializer call to set most of the read-only fields. The others are set, and reset, by the event subsystem during dispatch.

        Note that init() -- and the subclass-specific initWhatever() calls -- may be reinvoked. At least one initialization is required; repeated initializations overwrite the event with new values of their parameters.

        Specified by:
        initEvent in interface Event

      • getBubbles

        public boolean getBubbles()
        Specified by:
        getBubbles in interface Event
        Returns:
        true iff this Event is of a class and type which supports bubbling. In the generic case, this is True.

      • getCancelable

        public boolean getCancelable()
        Specified by:
        getCancelable in interface Event
        Returns:
        true iff this Event is of a class and type which (a) has a Default Behavior in this DOM, and (b)allows cancellation (blocking) of that behavior. In the generic case, this is False.

      • getCurrentTarget

        public EventTarget getCurrentTarget()
        Specified by:
        getCurrentTarget in interface Event
        Returns:
        the Node (EventTarget) whose EventListeners are currently being processed. During capture and bubble phases, this may not be the target node.

      • getEventPhase

        public short getEventPhase()
        Specified by:
        getEventPhase in interface Event
        Returns:
        the current processing phase for this event -- CAPTURING_PHASE, AT_TARGET, BUBBLING_PHASE. (There may be an internal DEFAULT_PHASE as well, but the users won't see it.)

      • getTarget

        public EventTarget getTarget()
        Specified by:
        getTarget in interface Event
        Returns:
        the EventTarget (Node) to which the event was originally dispatched.

      • getType

        public String getType()
        Specified by:
        getType in interface Event
        Returns:
        event name as a string

      • getTimeStamp

        public long getTimeStamp()
        Specified by:
        getTimeStamp in interface Event

      • stopPropagation

        public void stopPropagation()
        Causes exit from in-progress event dispatch before the next currentTarget is selected. Replaces the preventBubble() and preventCapture() methods which were present in early drafts; they may be reintroduced in future levels of the DOM.
        Specified by:
        stopPropagation in interface Event

      • preventDefault

        public void preventDefault()
        Prevents any default processing built into the target node from occurring.
        Specified by:
        preventDefault in interface Event
