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

---

merge

public void merge(SubPartitionInfo merged)

---

---

compareTo

public int compareTo(Object o)

"Note: this class has a natural ordering that is inconsistent with equals."

Specified by:

compareTo in interface Comparable

---
