- Method Detail
  - getMembersAtStart
```
Collection<org.infinispan.remoting.transport.Address> getMembersAtStart()
```
    Returns:
    
    Retrieves the list of members before rehashing started.
  - getMembersAtEnd
```
Collection<org.infinispan.remoting.transport.Address> getMembersAtEnd()
```
    Returns:
    
    Retrieves the list of members after rehashing ended.
  - getConsistentHashAtStart
```
ConsistentHash getConsistentHashAtStart()
```
    Returns:
    
    The current consistent hash that was installed prior to the rehash. It is used both for reading and writing before the rebalance.
  - getConsistentHashAtEnd
```
ConsistentHash getConsistentHashAtEnd()
```
    Returns:
    
    The consistent hash that will be installed after the rebalance. It will be used both for reading and writing once the rebalance is complete.
  - getUnionConsistentHash
```
@Deprecated
ConsistentHash getUnionConsistentHash()
```
    Deprecated.
    Since 9.0
    
    Returns:
    
    The union of the current and future consistent hashes.
  - getNewTopologyId
```
int getNewTopologyId()
```
    Returns:
    
    Retrieves the new topology id after rehashing was triggered.
