      lapisx.util.Debug.NoDebug

Enclosing class:

Debug

public static class Debug.NoDebug

extends Debug

Debug object that prints nothing and checks no assertions. Rarely useful.

It is preferable to use the singleton instance Debug.NONE rather than constructing new Debug.NoDebug instances. The Debug.NoDebug class is made public in case someone wants to extend it.
