Package oracle.spatial.network.lod

Class 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!
