Interface IConcurrentMap<K,V>

Type Parameters:

K - the type of keys maintained by this map

V - the type of mapped values

All Superinterfaces:

ConcurrentMap<K,V>, Map<K,V>

All Known Implementing Classes:

CacheRecordHashMap, ConcurrentReferenceHashMap, HeapNearCacheRecordMap, SampleableConcurrentHashMap, StorageSCHM

public interface IConcurrentMap<K,V>
extends ConcurrentMap<K,V>

A ConcurrentMap with applyIfAbsent function.

Memory consistency effects: As with other concurrent collections, actions in a thread prior to placing an object into a ConcurrentMap as a key or value happen-before actions subsequent to the access or removal of that object from the ConcurrentMap in another thread.
