Class WeakKeyIdentityMap
java.lang.Object
org.aspectbench.tm.runtime.internal.WeakKeyIdentityMap
- All Implemented Interfaces:
- java.util.Map
- Direct Known Subclasses:
- WeakKeyCollectingIdentityMap
- public class WeakKeyIdentityMap
- extends java.lang.Object
- implements java.util.Map
A Map implementation that uses reference identity of keys and holds weak references to its keys.
No purging of invalidated keys takes place.
Large parts of the Map interface aren't implemented as they are not necessary for the intended
application (tracematch indexing) and would be rather less than straightforward to implement.
