Class IteratorExecutableBindingImpl

java.lang.Object
  oracle.adfnmc.bindings.dbf.ControlBindingImpl
      oracle.adfnmc.bindings.dbf.IteratorExecutableBindingImpl

All Implemented Interfaces:

ControlBinding, IteratorAttributeValueListener, IteratorCollectionListener, IteratorKeyedAttributeValueListener, IteratorPositionListener, ELResolver

Direct Known Subclasses:

MethodIteratorBindingImpl

public class IteratorExecutableBindingImpl
extends ControlBindingImpl
implements IteratorPositionListener, IteratorKeyedAttributeValueListener, IteratorCollectionListener

Wraps an underlying BasicIterator instance and forwards events from it to child control bindings bound to that iterator, if the parent Binding Container is active. If the parent container is not active, it does not forward but instead sets a flag to refresh it's children when the container is active again
