| org.w3c.dom.UserDataHandler
| UserDataHandler | | public interface UserDataHandler (Code) | | When associating an object to a key on a node using setUserData
the application can provide a handler that gets called when the node the
object is associated to is being cloned or imported. 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.
