public interface MutationEvent extends Event
MutationEvent interface provides specific contextual
 information associated with Mutation events.
 See also the Document Object Model (DOM) Level 2 Events Specification.

relatedNode is used to identify a secondary node related
 to a mutation event. For example, if a mutation event is dispatched
 to a node indicating that its parent has changed, the
 relatedNode is the changed parent. If an event is
 instead dispatched to a subtree indicating a node was changed within
 it, the relatedNode is the changed node. In the case of
 the DOMAttrModified event it indicates the Attr node
 which was modified, added, or removed.String getPrevValue()
prevValue indicates the previous value of the
 Attr node in DOMAttrModified events, and of the
 CharacterData node in DOMCharacterDataModified events.String getNewValue()
newValue indicates the new value of the Attr
 node in DOMAttrModified events, and of the CharacterData
 node in DOMCharacterDataModified events.String getAttrName()
attrName indicates the name of the changed
 Attr node in a DOMAttrModified event.short getAttrChange()
attrChange indicates the type of change which triggered
 the DOMAttrModified event. The values can be MODIFICATION
 , ADDITION, or REMOVAL.void initMutationEvent(String typeArg, boolean canBubbleArg, boolean cancelableArg, Node relatedNodeArg, String prevValueArg, String newValueArg, String attrNameArg, short attrChangeArg)
initMutationEvent method is used to initialize the
 value of a MutationEvent created through the
 DocumentEvent interface. This method may only be called
 before the MutationEvent 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.typeArg - Specifies the event type.canBubbleArg - Specifies whether or not the event can bubble.cancelableArg - Specifies whether or not the event's default
   action can be prevented.relatedNodeArg - Specifies the Event's related Node.prevValueArg - Specifies the Event's
   prevValue attribute. This value may be null.newValueArg - Specifies the Event's
   newValue attribute. This value may be null.attrNameArg - Specifies the Event's
   attrName attribute. This value may be null.attrChangeArg - Specifies the Event's
   attrChange attribute Submit a bug or feature
