Interface UserDataHandler


public interface UserDataHandler
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.
