|IGPReplicaDescription||Provides access to members which set and return the properties of a GPReplicaDescription object.|
|IPersist||Defines the single method GetClassID, which is designed to supply the CLSID of an object that can be stored persistently in the system. IPersist is the base interface for three other interfaces: IPersistStorage, IPersistStream, and IPersistFile.|
|IXMLSerialize (esriSystem)||Provides access to members that XML serialize and deserialize an object to/from XML.|
|IXMLVersionSupport (esriSystem)||Provides access to members that help in serializing an object to different namespaces (versions).|
The GPReplicaDescription coclass is used during replica creation and data extraction to describe the data and schema to include. See the CreateReplica methods on the IGeoDataServer and IReplicationAgent interfaces,
It can also be accessed from existing replicas to determine the schema associated with a replica and the filters used. See the IGPReplica interface for more information.
