Class IDMap<K,V>

java.lang.Object
  extended by de.bsvrz.sys.funclib.losb.IDMap<K,V>
All Implemented Interfaces:
java.util.Map<K,V>

public class IDMap<K,V>
extends java.lang.Object
implements java.util.Map<K,V>

Map fuer das Mapping von Objekt-IDs auf Objekte. Wird im DataIdentTree benutzt. Erlaubt die Implementierung eigener Hashing-Strategien in Abhaengigkeit von der Map-Groesse.
