    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
