Class ErrorState

java.lang.Object
  org.lsst.ccs.subsystems.fcs.simulation.ErrorState

All Implemented Interfaces:

EngineState

public class ErrorState
extends java.lang.Object
implements EngineState

This is the concrete state where we know what to be done when the engine is in the state "error". It can only go in state "stop" when asked. It can't move.
