Subject RE: [classlib] TwoKeyHashMap
Date Sat, 22 Jul 2006 03:24:47 GMT
I'm all for removing it. The last time I looked through that code I came to
the same conclusion your questions infer. If I recall correctly, some of the
actual Map interface methods won't even work correctly if used. Also, I
believe the actual keys were just Strings, so concatenated Strings could
even be used.
