Class NoAction

java.lang.Object
  org.inria.ns.reflex.processor.core.AbstractAction
      org.inria.ns.reflex.processor.core.NoAction

All Implemented Interfaces:

Executable, Presentable, NamespaceContextFactory

Direct Known Subclasses:

LogicAction

public class NoAction
extends AbstractAction

At runtime, the NoAction does nothing. It may be used as a convenient action when unmarshalling. Actually, when none action is required, the null value must not be returned since an instance is always required.
