Thanks Henning,
I did not find it because I searched in the org.apache.commons.collections.map package. I knew the
shifted semantics of a multimap but after all it is still a map. Why isn't it put under the package
mentioned above? Wouldn't it be a good idea?
kind regards,
Achim

Hi list users,
As a newbie to commons collection I am searching for a MultiMap: A Map with add (another value to
key) and set (replace all old values for key) operations that allows mapping multiple values to a
single key.
I just found a map with multiple keys for identical values... A I blind?

A MultiMap is a Map with slightly different semantics. Putting a value
into the map will add the value to a Collection at that key. Getting a
value will return a Collection, holding all the values put to that
key.
