Class HashedMapIntKey<V>

java.lang.Object

com.grey.base.collections.HashedMapIntKey<V>

public final class HashedMapIntKey<V>
extends Object

Same idea as HashedMap, but hardcodes key type as primitive Ints, since generics don't support primitives (not without auto-boxing, which generates garbage for the GC).
For that reason, we don't implement the java.util.Map interface, as it expects its key-value parameters to be of type Object, and requires iterators that don't make sense in our context. We do match its functionality however, to the maximum extent that is appropriate.

See HashedMap.java for additional comments throughout the code, since the classes are so similiar.
The main design difference with HashedMap is obviously in getBucket().

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