- Method Detail
  - 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 -
  - 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 org.infinispan.commons.configuration.attributes.Matchable<KeyPartitioner>
