Interface FilterLocator

All Known Implementing Classes:

CarouselMain, FcsMain

public interface FilterLocator

This interface is to factorise code between main Module for carousel in standalone mode and main Module for whole fcs. In both case, during initialization of the subsystem, we want to update the carousel socket with the information on the location of the filters stored in Configuration System. In the configuration system, for each filter on the Carousel, we store the name of the socket this filter is on (socketName).

Method Detail

getCarousel

Carousel getCarousel()

Return the carousel Module of this filter locater.

Returns:

getFilterManager

FilterManager getFilterManager()

Return the filter manager of this filter locater.

Returns:

getPersistenceService

org.lsst.ccs.PersistencyService getPersistenceService()

checkFiltersLocation

@Command(type=QUERY,
         level=0,
         description="Check which filters are on Carousel and on which socket and update the sockets.",
         alias="locateFilters")
default void checkFiltersLocation()

This method updates the filters location in the Carousel sockets during the initialization phase.

saveFilterLocation

@Command(type=QUERY,
         level=0,
         description="Save filter location in filesystem (in ~ccs/etc/) or Configuration System.")
default void saveFilterLocation()

This method save the location of the filters in the filesystem or Configuration System. This command has to be executed before shutting down the subsystem to store filters location information. The goal is to be able to restart next time with the updated information.

getSubsystem

org.lsst.ccs.Subsystem getSubsystem()

getName

String getName()
