public interface Event
Event interface is used to provide contextual information 
 about an event to the handler processing the event. An object which 
 implements the Event interface is generally passed as the 
 first parameter to an event handler. More specific context information is 
 passed to event handlers by deriving additional interfaces from 
 Event which contain information directly relating to the 
 type of event they accompany. These derived interfaces are also 
 implemented by the object passed to the event listener. 
 See also the Document Object Model (DOM) Level 2 Events Specification.
| Modifier and Type | Field and Description | 
|---|---|
| static short | AT_TARGETThe event is currently being evaluated at the target 
  EventTarget. | 
| static short | BUBBLING_PHASEThe current event phase is the bubbling phase. | 
| static short | CAPTURING_PHASEThe current event phase is the capturing phase. | 
| Modifier and Type | Method and Description | 
|---|---|
| boolean | getBubbles()Used to indicate whether or not an event is a bubbling event. | 
| boolean | getCancelable()Used to indicate whether or not an event can have its default action 
 prevented. | 
| EventTarget | getCurrentTarget()Used to indicate the  EventTargetwhoseEventListenersare currently being processed. | 
| short | getEventPhase()Used to indicate which phase of event flow is currently being 
 evaluated. | 
| EventTarget | getTarget()Used to indicate the  EventTargetto which the event was 
 originally dispatched. | 
| long | getTimeStamp()Used to specify the time (in milliseconds relative to the epoch) at 
 which the event was created. | 
| java.lang.String | getType()The name of the event (case-insensitive). | 
| void | initEvent(java.lang.String eventTypeArg,
         boolean canBubbleArg,
         boolean cancelableArg)The  initEventmethod is used to initialize the value of anEventcreated through theDocumentEventinterface. | 
| void | preventDefault()If an event is cancelable, the  preventDefaultmethod is 
 used to signify that the event is to be canceled, meaning any default 
 action normally taken by the implementation as a result of the event 
 will not occur. | 
| void | stopPropagation()The  stopPropagationmethod is used prevent further 
 propagation of an event during event flow. |

EventTarget whose

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.void stopPropagation()
stopPropagation method is used prevent further 
 propagation of an event during event flow. If this method is called 
 by any EventListener the event will cease propagating 
 through the tree. The event will complete dispatch to all listeners 
 on the current EventTarget before event flow stops. This 
 method may be used during any stage of event flow.void preventDefault()
preventDefault method is 
 used to signify that the event is to be canceled, meaning any default 
 action normally taken by the implementation as a result of the event 
 will not occur. If, during any stage of event flow, the 
 preventDefault method is called the event is canceled. 
 Any default action associated with the event will not occur. Calling 
 this method for a non-cancelable event has no effect. Once 
 preventDefault has been called it will remain in effect 
 throughout the remainder of the event's propagation. This method may 
 be used during any stage of event flow.void initEvent(java.lang.String eventTypeArg,
             boolean canBubbleArg,
             boolean cancelableArg)
initEvent method is used to initialize the value of an 
 Event created through the DocumentEvent 
 interface. This method may only be called before the 
 Event has been dispatched via the 
 dispatchEvent method, though it may be called multiple 
 times during that phase if necessary. If called multiple times the 
 final invocation takes precedence. If called from a subclass of 
 Event interface only the values specified in the 
 initEvent method are modified, all other attributes are 
 left unchanged.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. It is 
   also strongly recommended that third parties adding their own 
   events use their own prefix to avoid confusion and lessen the 
   probability of conflicts with other new events.canBubbleArg - Specifies whether or not the event can bubble.cancelableArg - Specifies whether or not the event's default 
   action can be prevented.Copyright © 1999-2022 The Apache Software Foundation. All Rights Reserved.
