Direct Known Subclasses:

AdHocCommandHandler.SingleStage

public abstract class AdHocCommandHandler
extends AbstractAdHocCommand

Represents a command that can be executed locally from a remote location. This class must be extended to implement an specific ad-hoc command. This class provides some useful tools:

• Node
• Name
• Session ID
• Current Stage
• Available actions
• Default action

To implement a new command extend this class and implement all the abstract methods. When implementing the actions remember that they could be invoked several times, and that you must use the current stage number to know what to do.
