[jira] Created: (MAHOUT-255) Open hash set and map that plug into
java.util
Open hash set and map that plug into java.util
----------------------------------------------
Key: MAHOUT-255
URL: https://issues.apache.org/jira/browse/MAHOUT-255
Project: Mahout
Issue Type: New Feature
Components: Math
Affects Versions: 0.3
Reporter: Benson Margulies
Assignee: Benson Margulies
Aside from the primitive type issues, the usual java.util.HashMap/Set classes suffer from horrible storage inefficiency.
The Colt code can be adapted to add OpenHashSet<T> and OpenHashMap<K,V> that use open hashing and implement the full Collections interfaces.
