Class InsertionOrderedMap

  • All Implemented Interfaces:
    java.util.Map
    public class InsertionOrderedMap
extends java.lang.Object
implements java.util.Map
    Map with keys iterated in insertion order. This is similar to the Java 1.4 java.util.LinkedHashMap class, but compatible with earlier JVM versions. It also guarantees insertion ordering only for iterating through the key values, not for other iterations. This implementation is optimized for insert-only maps.
