Class FormDataListener

java.lang.Object

com.adobe.xfa.Obj

com.adobe.xfa.form.FormDataListener

All Implemented Interfaces:

Peer

public class FormDataListener
extends Obj

FormDataListener manages the mapping (i.e., binding) between an Element in the FormModel and its corresponding DataNode in the DataModel. An Element and DataNode that are bound will each be peered to a FormDataListener.
