public class ManagedIdentityConcurrentMap<K, V> extends ConcurrentReferenceHashMap
This is a basic implementation of a map able to forget its keys could be weak/soft/strong references. This bases on ConcurrentReferenceHashMap, thus it is safe for concurrency. This map compares keys through references.
K - the key typeV - the value type| Constructor and description |

ManagedIdentityConcurrentMap()Creates a new, empty map with the key weak reference |
ManagedIdentityConcurrentMap(int initialCapacity)Creates a new, empty map with the key weak reference and the specified initial capacity |
ManagedIdentityConcurrentMap(ConcurrentReferenceHashMap.ReferenceType keyType)Creates a new, empty map with the specified key reference type |
ManagedIdentityConcurrentMap(ConcurrentReferenceHashMap.ReferenceType keyType, int initialCapacity)Creates a new, empty map with the specified key reference type and initial capacity |
