`int`	`getPartition(java.lang.Object item, int partitionCount)`	Returns the partition ID of the given item.
`void`	`init(DefaultPartitionStrategy defaultPartitioning)`	Callback that injects the Hazelcast's default partitioning strategy into this partitioner so it can be consulted by the `Partitioner.getPartition(Object, int)` method.

public void init(@Nonnull

```
    Description copied from interface: Partitioner
    
    Callback that injects the Hazelcast's default partitioning strategy into this partitioner so it can be consulted by the Partitioner.getPartition(Object, int) method.
    The creation of instances of the Partitioner type is done in user's code, but the Hazelcast partitioning strategy only becomes available after the partitioner is deserialized on each target member. This method solves the lifecycle mismatch.
