Class OrderedIntKeyHashMap<V>

java.lang.Object

org.hsqldb.lib.IntKeyHashMap<V>

org.hsqldb.lib.OrderedIntKeyHashMap<V>

All Implemented Interfaces:

Map<Integer,V>

public class OrderedIntKeyHashMap<V>
extends IntKeyHashMap<V>
implements Map<Integer,V>

A Map of int primitives to Object values which maintains the insertion order of the key/value pairs and allows access by index. Iterators return the keys or values in the index order.
