 org.eclipse.jdi.internal.ValueCache
| ValueCache | | public class ValueCache (Code) | | This class is used to cache values.
It uses soft references to store cached values. Once a value is garbage collected by the VM,
the corresponding entry is removed from the cache on the next invocation of put() or get().
Note that WeakHashMap can't be used for this purpose because in WeakHashMap
soft references are only used for the keys, and values may not have 'strong' references
to keys otherwise they will never be garbage collected.
