Class Debug

java.lang.Object
  net.jangaroo.jooc.Debug

public final class Debug
extends Object

A class to provide debug facilities in java.

For assertTrue, to avoid evaluation of the boolean expression with debugging turned off on sun's java interpreter and with sun's javac use the following:

     Debug.assertTrue(Debug.enabled && anExpression, "error message");
 

The short-cut semantics of '&&' will guarantee that anExpression will not be evaluated if enabled is set to false.

Debug.print also won't print its argument if Debug.enabled is false. If the generation of the argument is already costly, you have to wrap it in an if-statement.
