java.lang.Object | +--org.apache.xerces.dom.events.EventImpl
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 | |
boolean |
getBubbles()
The bubbles property indicates whether or not an event is
a bubbling event. |
boolean |
getCancelable()
The cancelable property indicates whether or not an event
can have its default action prevented. |
Node |
getCurrentNode()
The currentNode property indicates the Node
whose EventListeners are currently being processed. |
short |
getEventPhase()
The eventPhase property indicates which phase of event
flow is currently being evaluated. |
EventTarget |
getTarget()
The target property indicates the EventTarget
to which the event was originally dispatched. |
long |
getTimeStamp()
The timeStamp specifies the time (in milliseconds relative
to the epoch) at which the event was created. |
java.lang.String |
getType()
The type property represents the event name as a string
property. |
void |
initEvent(java.lang.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. |
void |
preventDefault()
Prevents any default processing built into the target node from occurring. |
void |
stopPropagation()
Causes exit from in-progress event dispatch before the next currentNode is selected. |

public void initEvent(java.lang.String eventTypeArg, boolean canBubbleArg, boolean cancelableArg)
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.
initEvent

org.w3c.dom.events.Event
eventTypeArg
- Specifies the event type. This type may be any
event type currently defined in this specification or a new event
type.. The string must be an XML name . Any new event type must
not begin with any upper, lower, or mixed case version of the
string "DOM". This prefix is reserved for future DOM event sets.canBubbleArg
- Specifies whether or not the event can bubble.cancelableArg
- Specifies whether or not the event's default
action can be prevented.public boolean getBubbles()
Event
bubbles
property indicates whether or not an event is
a bubbling event. If the event can bubble the value is true, else the
value is false.getBubbles

cancelable
property indicates whether or not an event
can have its default action prevented. If the default action can be
prevented the value is true, else the value is false.getCancelable

public Node getCurrentNode()
Event
currentNode
property indicates the Node
whose EventListeners
are currently being processed. This
is particularly useful during capturing and bubbling.getCurrentNode

public long getTimeStamp()
Event
timeStamp
specifies the time (in milliseconds relative
to the epoch) at which the event was created. Due to the fact that
some systems may not provide this information the value of
timeStamp
may be not available for all events. When not
available, a value of 0 will be returned. Examples of epoch time are
the time of the system start or 0:0:0 UTC 1st January 1970.getTimeStamp
