Class IntHashMap

  • All Implemented Interfaces:
    java.util.Map
    public class IntHashMap
extends java.lang.Object
implements java.util.Map
    A Map that uses ints as the keys.

    Use just like any java.util.Map, except that the keys must be ints. This is much faster than creating a new Integer for each access.

    For non-Map access (faster) use the put(int, Object) method.

    This class implements Map for convenience, but this is not the most efficient usage.
