Class CopyOnWriteLinkedHashMap<K,V>

java.lang.Object

org.teiid.core.util.CopyOnWriteLinkedHashMap<K,V>

Type Parameters:

K -

V -

All Implemented Interfaces:

Serializable, Map<K,V>

public class CopyOnWriteLinkedHashMap<K,V>
extends Object
implements Map<K,V>, Serializable

Provides a mimimally concurrent (concurrent read/exclusive write) LinkedHashMap for use in read mostly situations. Does not support modification through entry/value collections. TODO: this may not be entirely thread safe as after the clone operations there's a chance that the referenced array is replaced by rehashing.
