org.lsst.ccs.framework.Module

org.lsst.ccs.subsystems.fcs.LoaderHookModule

All Implemented Interfaces:

Observer, org.lsst.ccs.config.ConfigurationBulkChangeHandler, org.lsst.ccs.framework.Configurable, org.lsst.ccs.framework.HasLifecycle, org.lsst.ccs.framework.SignalHandler, org.lsst.ccs.UsesSubsystem

public class LoaderHookModule
extends org.lsst.ccs.framework.Module

This is the model for a single hook in the loader. Each one is checked in CLOSED and OPENED position by 2 sensors. These sensors have to give a consistent response otherwise the hook is in ERROR. There is 4 hooks in the loader to hold a filter.
