Detailed Description

Conversion processing and value testing utilities for DCPS Information Repository identifiers.

This class encapsulates the conversion of a GUID_t value to and from other types used within OpenDDS. This includes the ability to create new RepoId values with a specific federation Id and Participant instance handle as well as extracting the Instance handle for an Entity from the RepoId value. Tests for Entity Kind as well as the type (User v. Builtin) of Entity are also included.

Currently the RepoId is a typedef for GUID_t. This class assumes responsibility for insulating users from future change.

Currently the RepoId is mapped from various internal values. These mappings are:

byte structure reference content ---- --------------------- -------------------------- 0 GUID_t.guidPrefix[ 0] == VendorId_t == 0x00 for OCI (used for OpenDDS) 1 GUID_t.guidPrefix[ 1] == VendorId_t == 0x03 for OCI (used for OpenDDS) 2 GUID_t.guidPrefix[ 2] == 0x00 3 GUID_t.guidPrefix[ 3] == 0x00

4 GUID_t.guidPrefix[ 4] == federation id (MS byte) 5 GUID_t.guidPrefix[ 5] == federation id 6 GUID_t.guidPrefix[ 6] == federation id 7 GUID_t.guidPrefix[ 7] == federation id (LS byte)

8 GUID_t.guidPrefix[ 8] == particpant id (MS byte) 9 GUID_t.guidPrefix[ 9] == particpant id 10 GUID_t.guidPrefix[10] == particpant id 11 GUID_t.guidPrefix[11] == particpant id (LS byte)

12 GUID_t.entityId.entityKey[ 0] == entity id[0] (MS byte) 13 GUID_t.entityId.entityKey[ 1] == entity id[1] 14 GUID_t.entityId.entityKey[ 2] == entity id[2] (LS byte) 15 GUID_t.entityId.entityKind == entity kind
