-/**
- * Soft reference objects, which are cleared at the discretion of the garbage
- * collector in response to memory demand.  Soft references are most often used
- * to implement memory-sensitive caches.
- *
- * <p> Suppose that the garbage collector determines at a certain point in time
- * that an object is <a href="package-summary.html#reachability">softly
- * reachable</a>.  At that time it may choose to clear atomically all soft
- * references to that object and all soft references to any other
- * softly-reachable objects from which that object is reachable through a chain
- * of strong references.  At the same time or at some later time it will
- * enqueue those newly-cleared soft references that are registered with
- * reference queues.
- *
- * <p> All soft references to softly-reachable objects are guaranteed to have
- * been cleared before the virtual machine throws an
- * <code>OutOfMemoryError</code>.  Otherwise no constraints are placed upon the
- * time at which a soft reference will be cleared or the order in which a set
- * of such references to different objects will be cleared.  Virtual machine
- * implementations are, however, encouraged to bias against clearing
- * recently-created or recently-used soft references.
- *
- * <p> Direct instances of this class may be used to implement simple caches;
- * this class or derived subclasses may also be used in larger data structures
- * to implement more sophisticated caches.  As long as the referent of a soft
- * reference is strongly reachable, that is, is actually in use, the soft
- * reference will not be cleared.  Thus a sophisticated cache can, for example,
- * prevent its most recently used entries from being discarded by keeping
- * strong referents to those entries, leaving the remaining entries to be
- * discarded at the discretion of the garbage collector.
