Class ClassMap<V>

java.lang.Object

io.requery.util.ClassMap<V>

Type Parameters:

V - type of mapped values

All Implemented Interfaces:

Map<Class<?>,V>

public class ClassMap<V>
extends Object
implements Map<Class<?>,V>

A map of class instances to values. Maps classes to values in such a way that if you have a class B that extends A:

 
      map.put(A.class, "any A");
      String s = map.get(B.class);
 
 

returns "any A" since B extends A. Null keys aren't allowed.
