 org.apache.xerces.dom.events.EventImpl
All known Subclasses: org.apache.xerces.dom.events.MutationEventImpl, org.apache.xerces.dom.events.UIEventImpl,
| EventImpl | | public class EventImpl implements Event(Code) | | 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.

| Method Summary | |
| public boolean | getBubbles()
true iff this Event is of a class and type which supportsbubbling. | | public boolean | getCancelable()
true iff this Event is of a class and type which (a) has aDefault Behavior in this DOM, and (b)allows cancellation (blocking)of that behavior. | | public EventTarget | getCurrentTarget()
the Node (EventTarget) whose EventListeners are currentlybeing processed. | | public short | getEventPhase()
the current processing phase for this event -- CAPTURING_PHASE, AT_TARGET, BUBBLING_PHASE. | | public EventTarget | getTarget()
| | public long | getTimeStamp()
| | public String | getType()
| | 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. | | public void | preventDefault()
Prevents any default processing built into the target node from
occurring. | | public void | stopPropagation()
Causes exit from in-progress event dispatch before the next
currentTarget is selected. |
| eventPhase | | public short eventPhase(Code) | | |
| initializedbubblescancelable | | public boolean initializedbubblescancelable(Code) | | |
| stopPropagationpreventDefault | | public boolean stopPropagationpreventDefault(Code) | | |
| timeStamp | | protected long timeStamp(Code) | | |
| getBubbles | | public boolean getBubbles()(Code) | | true iff this Event is of a class and type which supportsbubbling. In the generic case, this is True. |
| getCancelable | | public boolean getCancelable()(Code) | | true iff this Event is of a class and type which (a) has aDefault Behavior in this DOM, and (b)allows cancellation (blocking)of that behavior. In the generic case, this is False. |
| getCurrentTarget | | public EventTarget getCurrentTarget()(Code) | | the Node (EventTarget) whose EventListeners are currentlybeing processed. During capture and bubble phases, this may not bethe target node. |
| getEventPhase | | public short getEventPhase()(Code) | | the current processing phase for this event -- CAPTURING_PHASE, AT_TARGET, BUBBLING_PHASE. (There may bean internal DEFAULT_PHASE as well, but the users won't see it.) |
| getTarget | | public EventTarget getTarget()(Code) | | the EventTarget (Node) to which the event was originallydispatched. |
| getTimeStamp | | public long getTimeStamp()(Code) | | |
| initEvent | | public void initEvent(String eventTypeArg, boolean canBubbleArg, boolean cancelableArg)(Code) | | 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.
|
| preventDefault | | public void preventDefault()(Code) | | Prevents any default processing built into the target node from
occurring.
|
| stopPropagation | | public void stopPropagation()(Code) | | 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.
