Subject [collections] CollectionUtils.getCardinalityMap JavaDoc
Date Sun, 07 Sep 2003 01:35:41 GMT
In CollectionUtils.getCardinalityMap the documentation notes the meaning of an entry that maps
to null but I don't see how any such entry can exist in the returned map as all the keys in
the map come from the collection parameter and will map to >=1. Have I missed something?
