  com.hazelcast.util.counters.MwCounter

All Implemented Interfaces:

Counter

public final class MwCounter
extends Object
implements Counter

A Counter that is thread-safe; so can be incremented by multiple threads concurrently. The MwCounter is not meant for a huge amount of contention. In that case it would be better to create a counter on the LongAdder. This counter does not provide padding to prevent false sharing.
