public class GuidPrefix

Every Participant has GUID (prefix, ENTITYID_PARTICIPANT), where the constant ENTITYID_PARTICIPANT is a special value defined by the RTPS protocol. Its actual value depends on the PSM. The implementation is free to choose the prefix, as long as every Participant in the Domain has a unique GUID.
