Class GridSynchronizedMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

java.util.concurrent.ConcurrentHashMap<K,V>

org.apache.ignite.internal.util.GridSynchronizedMap<K,V>

All Implemented Interfaces:

Externalizable, Serializable, ConcurrentMap<K,V>, Map<K,V>

public class GridSynchronizedMap<K,V>
extends ConcurrentHashMap<K,V>
implements Externalizable

Synchronized map for cache values that is safe to update in-place. Main reason for this map is to provide snapshot-guarantee for serialization and keep concurrent iterators.
