org.scopemvc.util
Class Debug  

java.lang.Object
  org.scopemvc.util.Debug

---

public final class Debug

extends java.lang.Object

A (very simple) general purpose Debug class for assertion checking. e.g.

 if (Debug.ON) Debug.assert(thing != null);
 if (Debug.ON) Debug.assert(thing != null, "thing is null");
 

The ON boolean is a static final so that setting it to false and rebuilding the project will strip all debug code from the binaries.
