Buddy Class Reference

Detailed Description

Buddy implements mutual relationship between objects.

Relationship is established with hello(). Then goodbye() will be called for all buddies, when the object is destroyed.

This is the only thing that the class does. This class can be used if an object needs to know when another object is destroyed, and vice-versa.
