Interface MutationEvent

All Superinterfaces:
  Event

public interface MutationEvent
extends Event

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

See also the Document Object Model (DOM) Level 2 Events Specification.

Since:
  DOM Level 2

Field Summary
`static short` `ADDITION` The `Attr` was just added.
`static short` `MODIFICATION` The `Attr` was modified in place.
`static short` `REMOVAL` The `Attr` was just removed.

Fields inherited from interface org.w3c.dom.events.Event
`AT_TARGET, BUBBLING_PHASE, CAPTURING_PHASE`

Method Summary
`short` `getAttrChange()` `attrChange` indicates the type of change which triggered the DOMAttrModified event.
`java.lang.String` `getAttrName()` `attrName` indicates the name of the changed `Attr` node in a DOMAttrModified event.
`java.lang.String` `getNewValue()` `newValue` indicates the new value of the `Attr` node in DOMAttrModified events, and of the `CharacterData` node in DOMCharacterDataModified events.
`java.lang.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(java.lang.String typeArg, boolean canBubbleArg, boolean cancelableArg, Node relatedNodeArg, java.lang.String prevValueArg, java.lang.String newValueArg, java.lang.String attrNameArg, short attrChangeArg)` The `initMutationEvent` method is used to initialize the value of a `MutationEvent` created through the `DocumentEvent` interface.

Field Detail

### MODIFICATION

    public static final short MODIFICATION

  The `Attr` was modified in place.

### ADDITION

    public static final short ADDITION

  The `Attr` was just added.

### REMOVAL

    public static final short REMOVAL

  The `Attr` was just removed.

Method Detail

### getRelatedNode

    public 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

    public java.lang.String getPrevValue()

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

### getNewValue

    public java.lang.String getNewValue()

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

### getAttrName

    public java.lang.String getAttrName()

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

### getAttrChange

    public short getAttrChange()

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

### initMutationEvent

    public void initMutationEvent(java.lang.String typeArg,
                                  boolean canBubbleArg,
                                  boolean cancelableArg,
                                  Node relatedNodeArg,
                                  java.lang.String prevValueArg,
                                  java.lang.String newValueArg,
                                  java.lang.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
