Method Summary

Modifier and Type	Method	Description
default int	applyAsInt(Object value)
int	getSegment(Object key)	Obtains the segment for a key.
default void	init(HashConfiguration configuration)	Initialization.
default void	init(KeyPartitioner other)
default boolean	matches(KeyPartitioner other)

Method Details

init

default void init(HashConfiguration configuration)

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).

Parameters:

configuration -

init

default void init(KeyPartitioner other)

applyAsInt

default int applyAsInt(Object value)

Specified by:

applyAsInt in interface ToIntFunction<Object>

getSegment

int getSegment(Object key)

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

matches

default boolean matches(KeyPartitioner other)

Specified by:

matches in interface Matchable<KeyPartitioner>
