Subject [Collections] MultiKeyMap vs concatenating keys that are strings
Date Fri, 21 Oct 2005 18:08:53 GMT

If I am building a map with a compound key composed of say 3 strings , 
is there any advantage to using MultiKeyMap over a regular Hash(ed)Map
with the key = key1+"_"+key2+"_"+key3;


thanks in advance
