PTDiffusionLogging Class Reference

Introduction

Logging provides access to debug information that can be enabled at runtime.

Changes to properties here have immediate effect on the verbosity or otherwise of log output.

The format of output log messages is subject to change. Messages are sent to the Apple System Log facility via the Foundation framework's NSLog function.
