Class MultiValueTable<K,V>

java.lang.Object

freenet.support.MultiValueTable<K,V>

public class MultiValueTable<K,V>
extends java.lang.Object

A hashtable that can store several values for each entry. FIXME improve efficiency - map to Object internally and either use a single V or an ArrayList of V. Then take over where we do this in the code e.g. PrioritizedTicker.
