[jira] [Created] (COLLECTIONS-461) splitmap.TransformedMap is not really a Map

Sebb created COLLECTIONS-461:
--------------------------------

             Summary: splitmap.TransformedMap is not really a Map
                 Key: COLLECTIONS-461
                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-461
             Project: Commons Collections
          Issue Type: Bug
            Reporter: Sebb


splitmap.TransformedMap is part of the Get/Put hierarchy, but it does not behave like a proper Java Map. 

In particular, java.util.Map.put(K, V) returns V.
However the collections Put interface returns Object.
As far as I can tell, this was done in order to be able to include TransformedMap in the hiearchy. But the side effect is to break the generics for all the non-transformer maps in the hierarchy.

Maybe there should be a separate PutTransformed interface which has the appropriate generic types, i.e.

public T put(K key, V value)
