public interface UserDataHandler
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.
Modifier and Type | Field | Description |
---|---|---|
static short |
NODE_ADOPTED |
The node is adopted, using
Document.adoptNode() . |
static short |
NODE_CLONED |
The node is cloned, using
Node.cloneNode() . |
static short |
NODE_DELETED |
The node is deleted.
|
static short |
NODE_IMPORTED |
The node is imported, using
Document.importNode() . |
static short |
NODE_RENAMED |
The node is renamed, using
Document.renameNode() . |
Modifier and Type | Method | Description |
---|---|---|
void |
handle(short operation,
String key,
Object data,
Node src,
Node dst) |
This method is called whenever the node for which this handler is
registered is imported or cloned.

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.
