java.lang.Object
- org.onemind.commons.java.datastructure.InheritableValueMap

```
public class InheritableValueMap
extends java.lang.Object
```
Associate a class and an value object and resolve the mapping through the class hierachy. For example, if a value object A is assosiated with Number class that means it is associated with the Number class and all the subclasses of object class. However, if a mapping exists for Integer, the InheritableValueMap will return the value object associated for the Integer. The stopClass controls when the InheritableValueMap stop resolving mapping and return null (when c==stopClass.getSuperClass()). The stopClass also control the hierachy of object that can be added the the map - meaning stopClass.isAssignableFrom(c) must evaluate to true when c is added as mapping key.
