Interface MutationEvent

All Superinterfaces:: Event

public interface MutationEvent extends Event

The MutationEvent interface provides specific contextual information associated with Mutation events.

Since:: 1.5, DOM Level 2

Field Summary

Modifier and Type	Field	Description
`static final short`	`ADDITION`	The `Attr` was just added.
`static final short`	`MODIFICATION`	The `Attr` was modified in place.

Fields declared in interface Event

AT_TARGET, BUBBLING_PHASE, CAPTURING_PHASE

Modifier and Type	Field	Description
`static final short`	`AT_TARGET`	The event is currently being evaluated at the target `EventTarget`.
`static final short`	`BUBBLING_PHASE`	The current event phase is the bubbling phase.
`static final short`	`CAPTURING_PHASE`	The current event phase is the capturing phase.

Method Summary

Modifier and Type	Method	Description
`short`	`getAttrChange()`	`attrChange` indicates the type of change which triggered the DOMAttrModified event.
`String`	`getAttrName()`	`attrName` indicates the name of the changed `Attr` node in a DOMAttrModified event.
`String`	`getNewValue()`	`newValue` indicates the new value of the `Attr` node in DOMAttrModified events, and of the `CharacterData` node in DOMCharacterDataModified events.
`String`	`getPrevValue()`	`prevValue` indicates the previous value of the `Attr` node in DOMAttrModified events, and of the `CharacterData` node in DOMCharacterDataModified events.
`Node`	`getRelatedNode()`	`relatedNode` is used to identify a secondary node related to a mutation event.
`void`	`initMutationEvent(String typeArg, boolean canBubbleArg, boolean cancelableArg, Node relatedNodeArg, String prevValueArg, String newValueArg, String attrNameArg, short attrChangeArg)`	The `initMutationEvent` method is used to initialize the value of a `MutationEvent` created through the `DocumentEvent` interface.

Methods declared in interface Event

getBubbles, getCancelable, getCurrentTarget, getEventPhase, getTarget, getTimeStamp, getType, initEvent, preventDefault, stopPropagation

Modifier and Type	Method	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 `EventTarget` whose `EventListeners` are currently being processed.
`short`	`getEventPhase()`	Used to indicate which phase of event flow is currently being evaluated.
`EventTarget`	`getTarget()`	Used to indicate the `EventTarget` to 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.
`String`	`getType()`	The name of the event (case-insensitive).
`void`	`initEvent(String eventTypeArg, boolean canBubbleArg, boolean cancelableArg)`	The `initEvent` method is used to initialize the value of an `Event` created through the `DocumentEvent` interface.
`void`	`preventDefault()`	If an event is cancelable, the `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.
`void`	`stopPropagation()`	The `stopPropagation` method is used prevent further propagation of an event during event flow.

Field Details

MODIFICATION

ADDITION

static final short ADDITION

REMOVAL

static final short REMOVAL

The Attr was just removed.

Method Details

getRelatedNode

Node getRelatedNode()

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.

getPrevValue

String getPrevValue()

prevValue indicates the previous value of the Attr node in DOMAttrModified events, and of the CharacterData node in DOMCharacterDataModified events.

getNewValue

String getNewValue()

newValue indicates the new value of the Attr node in DOMAttrModified events, and of the CharacterData node in DOMCharacterDataModified events.

getAttrName

String getAttrName()

attrName indicates the name of the changed Attr node in a DOMAttrModified event.

getAttrChange

short getAttrChange()

attrChange indicates the type of change which triggered the DOMAttrModified event. The values can be MODIFICATION , ADDITION, or REMOVAL.

initMutationEvent

void initMutationEvent(String typeArg, boolean canBubbleArg, boolean cancelableArg, Node relatedNodeArg, String prevValueArg, String newValueArg, String attrNameArg, short attrChangeArg)

The 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.

Parameters:: 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
