Class LongHashMap<V>

java.lang.Object

oracle.spatial.network.lod.LongHashMap<V>

Direct Known Subclasses:

LongHashTable, LongLinkedHashMap

public class LongHashMap<V>
extends java.lang.Object

This is a bare-bones, application specific, optimized hash table implementation. We feel this will perform better than the java.util.HashMap implementation for our application both in terms of execution time and memory usage. This is an UNSYNCHRONIZED IMPLEMENTATION!
