isLocal

boolean isLocal(Object key)

locate

List<Address> locate(Object key)

Locates a key in a cluster. The returned addresses may not be owners of the keys if a rehash happens to be in progress or is pending, so when querying these servers, invalid responses should be checked for and the next address checked accordingly.

Parameters:

key - key to test

Returns:

a list of addresses where the key may reside

locateAll

Map<Object,List<Address>> locateAll(Collection<Object> keys)

Locates a list of keys in a cluster. Like locate(Object) the returned addresses may not be owners of the keys if a rehash happens to be in progress or is pending, so when querying these servers, invalid responses should be checked for and the next address checked accordingly.

Parameters:

keys - list of keys to test

Returns:

a list of addresses where the key may reside
