Class IntHashMap

java.lang.Object
  org.apache.ibatis.ognl.IntHashMap

All Implemented Interfaces:

Map

public class IntHashMap
extends Object
implements 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.
