Interface Summary

IntSet

A generic set of ints that has an efficient implementation, BitSet, which is a compressed bitset and is useful for ints that are small, for example less than 500 or so, and w/o many ranges.

Class Summary

Barrier	A very simple barrier wait.
BitSet	A BitSet to replace java.util.BitSet.
Graph	A generic graph with edges; Each node as a single Object payload.
Graph.Node
IntArrayList	An ArrayList based upon int members.
Interval	An immutable inclusive interval a..b
IntervalSet	A set of integers that relies on ranges being common to do "run-length-encoded" like compression (if you view an IntSet like a BitSet with runs of 0s and 1s).
MultiMap<K,V>	A hash table that maps a key to a list of elements not just a single.
MutableInteger	Java won't let you modify an Integer; not sure how that's more efficient, but...here's one that let's you modify it.
OrderedHashSet<T>	A HashMap that remembers the order that the elements were added.
