public abstract class GameModule

extends AbstractConfigurable

implements CommandEncoder

The GameModule class is the base class for a VASSAL module. It is the root of the Buildable containment hierarchy. Components which are added directly to the GameModule are contained in the VASSAL.build.module package It is a singleton, and contains access points for many other classes, such as DataArchive, ServerConnection, Logger, and Prefs
