SUMMARY: NESTED | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
When associating an object to a key on a node using
Node.setUserData()
the application can provide a handler
that gets called when the node the object is associated to is being
cloned, imported, or renamed. This can be used by the application to
implement various behaviors regarding the data it associates to the DOM
nodes. This interface defines that handler.
See also the Document Object Model (DOM) Level 3 Core Specification.
Field Summary | |
static short |
NODE_CLONED
The node is cloned. |
static short |
NODE_DELETED
The node is deleted. |
static short |
NODE_IMPORTED
The node is imported. |
static short |
NODE_RENAMED
The node is renamed. |
Method Summary | |
void |
handle(short operation,
java.lang.String key,
java.lang.Object data,
Node src,
Node dst)
This method is called whenever the node for which this handler is registered is imported or cloned. |
Field Detail |
public static final short NODE_CLONED
public static final short NODE_IMPORTED
public static final short NODE_DELETED
Note: This may not be supported or may not be reliable in certain environments, such as Java, where the implementation has no real control over when objects are actually deleted.
public static final short NODE_RENAMED
