Field Detail

f_mapGUID

protected final Map<Member,String[]> f_mapGUID

The Map of registered GUIDs, keyed by member.

m_cPartitions

protected int m_cPartitions

The partition-count.

m_asGUIDNewest

protected String[] m_asGUIDNewest

The resolved list of the newest GUIDs, indexed by partition-id.

m_mapResolved

protected Map<Member,PartitionSet> m_mapResolved

The resolved map of members to the associated set of partitions.

m_partsUnresolved

protected PartitionSet m_partsUnresolved

The PartitionSet containing partitions that don't have corresponding GUIDs.

m_fSharedStorage
