| org.w3c.dom.UserDataHandler
| UserDataHandler | | public interface UserDataHandler (Code) | | 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.
