Class InsertionOrderedMap
java.lang.Object
org.jibx.util.InsertionOrderedMap
- All Implemented Interfaces:
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.
