Method Detail

init

public void init(HashConfiguration configuration)

Description copied from interface: KeyPartitioner

Initialization.

The partitioner can also use injection to access other cache-level or global components. This method will be called before any other injection methods.

Does not need to be thread-safe (Infinispan safely publishes the instance after initialization).

Specified by:

init in interface KeyPartitioner

getSegment

public int getSegment(Object key)

Description copied from interface: KeyPartitioner

Obtains the segment for a key. Must be thread-safe.

Specified by:

getSegment in interface KeyPartitioner

getHash

public Hash getHash()

getSegmentEndHashes

public List<Integer> getSegmentEndHashes()

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode
