Class ncsa.habanero.granted.ActionRequest 

java.lang.Object
   |
   +----ncsa.habanero.granted.ActionRequest
public abstract class ActionRequest
extends Object
implements Answerable
The ActionRequest is the base class for a hierarchy of classes which present a request to the Arbitrator to execute an Action. The base class asserts that there is a target and an action, but does not allocate storage for either. This allows for cases in which the ActionRequest does not explicitly store a single action or target, such as when there are a number of possible actions, or when the action itself references the target.
