Enclosing class:

Debug

public static class Debug.Quiet

extends Debug.Verbose

Debug object that only prints exception stack traces and assertion failures. No other debug messages are printed. Assertion failures only print a report, without throwing an exception. This object is a good default debug level, even for released code.

If you want to print to System.err, just use the singleton instance Debug.QUIET rather than constructing a new Debug.Quiet instance.
