public static final short NODE_CLONED

The node is cloned, using Node.cloneNode().

Field Value:

1

public static final short NODE_DELETED

The node is 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.

Field Value:

3

public static final short NODE_IMPORTED

The node is imported, using Document.importNode().

Field Value:

2

public static final short NODE_RENAMED

The node is renamed, using Document.renameNode().

Field Value:

public 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.
DOM applications must not raise exceptions in a UserDataHandler. The effect of throwing exceptions from the handler is DOM implementation dependent.

Parameters:

operation - Specifies the type of operation that is being performed on the node.

key - Specifies the key for which this handler is being called.

data - Specifies the data for which this handler is being called.

src - Specifies the node being cloned, adopted, imported, or renamed. This is null when the node is being deleted.

dst - Specifies the node newly created if any, or null.
