Class SafeDbfReference<T>

Object

oracle.maf.impl.amx.SafeDbfReference<T>

public class SafeDbfReference<T>
extends Object

Allows for safely referencing data binding framework objects, making sure they are not used after the binding context has been changed. The data binding framework objects like AmxTreeBinding have corruption issues when used after the binding container has been changed. To prevent using these objects, this class ensures the binding container has not changed. If it has, it will not return the value.
