                                  java.util.WeakHashMap<T,java.lang.ref.WeakReference<T>> cache)

Some objects can be shared, if "equal", rather than creating duplicates, if they're read-only. This may in general be beneficial by reducing the size of the "working set" via more sharing of read-only objects. Users should insure the read-only property. This routine allows a) creating a potentially sharable object b) checking to see if we already have an "equal" one, and c) if so, using that and allowing the just created one to be GC'd.

Type Parameters:

T - the type of the cached object

Parameters:

obj - - the object to use a cached substitute for, if one exists

cache - - the cache

Returns:

- the object or a cached version of it.
