Examples of org.infinispan.atomic.AtomicHashMap

org.infinispan.atomic.AtomicHashMap
The default implementation of {@link AtomicMap}. Note that this map cannot be constructed directly, and callers should obtain references to AtomicHashMaps via the {@link AtomicMapLookup} helper. This helper will ensure properconcurrent construction and registration of AtomicMaps in Infinispan's data container. E.g.:

AtomicMap<String, Integer> map = AtomicMapLookup.getAtomicMap(cache, "my_atomic_map_key");

Note that for replication to work properly, AtomicHashMap updates must always take place within the scope of an ongoing JTA transaction or batch (see {@link Cache#startBatch()}).
