Class HashedSetInt

java.lang.Object

com.grey.base.collections.HashedSetInt

public final class HashedSetInt
extends Object

Same idea as HashedSet, except with integer keys. More to the point, the JDK collections don't support primitives anyway (not without auto-boxing, which generates garbage for the GC).

Beware that this class is single-threaded and non-reentrant.
