Class ConsoleCommandShell

java.lang.Object

org.lsst.ccs.subsystem.shell.ConsoleCommandShell

All Implemented Interfaces:

org.lsst.ccs.messaging.AgentPresenceListener, org.lsst.ccs.services.AgentLockService.AgentLevelListener, org.lsst.ccs.services.AgentLockService.AgentLockUpdateListener

public class ConsoleCommandShell
extends Object
implements org.lsst.ccs.messaging.AgentPresenceListener, org.lsst.ccs.services.AgentLockService.AgentLevelListener, org.lsst.ccs.services.AgentLockService.AgentLockUpdateListener

JLine-based command shell. Re-factored version of ConsoleBusMaster - allows creation of a command console without creating a subsystem.

Static methods of this class can be used to either run the shell standalone or construct JLineShell for embedding into the graphical console.
