Class IndexedMap<K,V>

java.lang.Object

jpa.tools.swing.IndexedMap<K,V>

Type Parameters:

K -

V -

All Implemented Interfaces:

Map<K,V>

public class IndexedMap<K,V>
extends Object
implements Map<K,V>

A map with indexed access. The keys are indexed in their order of insertion. The index of a given key is stable. It never changes unless the map is cleared. On remove(k), the key is not removed, but its value is nullified. Then indexOf(k) will return -1.
