Initializes the subsystem.

Specified by:

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

postStart

public void postStart()

Starts the subsystem.

Specified by:

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

connected

public void connected(org.lsst.ccs.bus.data.AgentInfo... agents)

Listens for the arrival of the refrigeration subsystem.

Specified by:

connected in interface org.lsst.ccs.messaging.AgentPresenceListener

Parameters:

agents - Array of agents present

disconnected

public void disconnected(org.lsst.ccs.bus.data.AgentInfo... agents)

Listens for the departure of the refrigeration subsystem.
