IHASnapshotDigestResponse	Message used to communicate the digest of an snapshot file associated with a specific commit point.
IHASnapshotRequest	Message requesting a snapshot.
IHASnapshotResponse	The message when a snapshot has been taken.
IHASyncRequest	An abstract message for either re-synchronizing (incremental catch up) or re-building (ground up rebuild).
IHAWriteMessage	A message carrying RMI metadata about a payload which will be replicated using a socket-level transfer facility.
IHAWriteMessageBase	Interface for RMI messages used to communicate metadata about a raw data transfer occurring on a socket channel.
IHAWriteSetStateRequest	Request metadata about the current write set from the quorum leader.
IHAWriteSetStateResponse	Message communicates the state of the current write set on the quorum leader.
