Package com.atlassian.bamboo.utils.map

Class TypedIdentityMap<V>

java.lang.Object

com.atlassian.bamboo.utils.map.TypedIdentityMap<V>

Type Parameters:

V - value

All Implemented Interfaces:

ConcurrentMap<Key<? extends V>,V>, Map<Key<? extends V>,V>

public class TypedIdentityMap<V>
extends Object
implements ConcurrentMap<Key<? extends V>,V>

A map which maintains its values type safety through a Key instance without having to cast from References inside the map are automatically garbage collected when the reference to Key is lost. See WeakHashMap. Example: TypedIdentityMap<Object> map = new TypedIdentityMap<Object>(); Key<Foo> fooKey = Key.create(Foo.class); map.putIfAbsent(fooKey, new Foo()); Foo foo = map.getValue(fooKey);
