Package org.lsst.ccs.bus.messages Description

This package defines all the standard messages for the CCS buses. All messages are serialized when sent over the buses. For this reason it is important that all classes define a SerialVersionUID. This id will have to be modified by the developer only when backward incompatible changes are introduced.
