public class SoftReferenceCache
extends Object
implements Cache
Cache which is cleared according to memory pressure. This
is simply a wrapper around java.lang.ref.SoftReference, and
the performance will depend on the behaviour of SoftReference
on your platform.
Construct a temporary reference to an object. The reference
persists until it becomes dereferenced itself, it is explicitly
cleared by the user, or the cache determines that it is a
candidate for disposal.
