Class Retrieval

java.lang.Object
  java.util.AbstractMap<K,V>
      java.util.HashMap<Instance,Similarity>
          de.dfki.mycbr.core.retrieval.Retrieval

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Runnable, java.util.Map<Instance,Similarity>

public class Retrieval
extends java.util.HashMap<Instance,Similarity>
implements java.lang.Runnable

A retrieval has a retrieval method and a retrieval engine. When specifying a case base and a query you can retrieve a similarity value between the query and each case in the case base.
