Field Detail

subPartitionName

public String subPartitionName

Name of the current sub-partition (will be used to create a JGroups group)

subPartitionMergedNames

public HashSet subPartitionMergedNames

When sub-partitions are merged, some names will disappear (eg. Merge G1 and G2 in G1) this structure remembers the removed named so that HAPartition can know which new group they should join

memberNodeNames

public ArrayList memberNodeNames

List of nodes part of this sub-partition
