Class ReferenceMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

org.redisson.misc.ReferenceMap<K,V>

All Implemented Interfaces:

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

public class ReferenceMap<K,V>
extends AbstractMap<K,V>
implements ConcurrentMap<K,V>

Concurrent hash map that wraps keys and/or values in SOFT or WEAK references. Does not support null keys or values. Uses identity equality for weak and soft keys. Supports remove listener
