org.infinispan.atomic
Class FineGrainedAtomicHashMapProxy<K,V>

java.lang.Object
  org.infinispan.batch.AutoBatchSupport
      org.infinispan.atomic.AtomicHashMapProxy<K,V>
          org.infinispan.atomic.FineGrainedAtomicHashMapProxy<K,V>

Type Parameters:

K - the type of keys maintained by this map

V - the type of mapped values

All Implemented Interfaces:

Map<K,V>, AtomicMap<K,V>, FineGrainedAtomicMap<K,V>

public class FineGrainedAtomicHashMapProxy<K,V>
extends AtomicHashMapProxy<K,V>
implements FineGrainedAtomicMap<K,V>

A layer of indirection around an FineGrainedAtomicMap to provide consistency and isolation for concurrent readers while writes may also be going on. The techniques used in this implementation are very similar to the lock-free reader MVCC model used in the MVCCEntry implementations for the core data container, which closely follow software transactional memory approaches to dealing with concurrency.

Typically proxies are only created by the AtomicMapLookup helper, and would not be created by end-user code directly.
