Class FakeFilterHolder

java.lang.Object

org.lsst.ccs.subsystems.fcs.FakeFilterHolder

All Implemented Interfaces:

org.lsst.ccs.framework.HasLifecycle, FilterHolder

public class FakeFilterHolder
extends Object
implements FilterHolder, org.lsst.ccs.framework.HasLifecycle

This class is a model for the fakeAutochanger that we use on loader and carousel test bench in standalone mode. As there is no autochanger, a numeric sensor is setup to simulate that the autochanger holds the filter at STANDBY or HANDOFF position. It'subs also a model for the fakeCarousel and the fakeLoader in autochanger-standalone subsystem. FakeFilterHolder implements interface FilterHolder. In the whole FCS, carousel, autochanger and loader implements FilterHolder too.

Method Detail

init

public void init()

Specified by:

init in interface org.lsst.ccs.framework.HasLifecycle

isHoldingFilter

@Command(type=QUERY,
         level=0,
         description="Return true if the fake autochanger is holding the filter. This command doesn\'t read again the sensor.")
public boolean isHoldingFilter()

Return true if the fake filter holder is holding the filter. This command doesn't read again the sensor.

Specified by:

isHoldingFilter in interface FilterHolder

Returns:

updateStateWithSensors

@Command(type=ACTION,
         level=1,
         description="Update clamp state in reading sensors.")
public void updateStateWithSensors()

This methods updates the field holdingFilter in reading the holding filter sensor. Then it published status data on the STATUS bus.

Specified by:

updateStateWithSensors in interface FilterHolder

Throws:

FcsHardwareException

publishData

public void publishData()

Publish Data on status bus for trending data base and GUIs.

isAtHandoff

public boolean isAtHandoff()

For the fake autochanger there is no autochanger trucks, so the position has not a real meaning. The autochanger is supposed to be at HANDOFF. Idem for fakeCarousel and fakeLoader.

Specified by:

isAtHandoff in interface FilterHolder

Returns:

isAtStandby

public boolean isAtStandby()

For the fake autochanger there is no autochanger trucks, so the position has not a real meaning. The autochanger is supposed to be at STANDBY. Idem for fakeCarousel and fakeLoader.

Specified by:

isAtStandby in interface FilterHolder

Returns:
