public class OMAGServerPlatformInstanceMap
extends Object

OMAGServerPlatformInstanceMap provides part of the mapping for inbound REST requests to the appropriate service instances for the requested server. It manages the server name to server instance mapping. The map is maintained in a static so it is scoped to the class loader. Instances of this class call the synchronized static methods to work with the map.
