Pt Namespace Reference

Detailed Description

This module is the basis for all other modules of the framework It has no dependency to any system specific libraries except the standard c++ library. It provides some basic types, support for byte-order handling, atomic integer operations, type-traits, an unicode string and character class, serialization and a signals/delegates based callback mechanism.
