Code-Generator Registry
Derived classes register via a static registration mechanism to provide an application-invokable constructor. The static registry records the constructor with a std::string typename as identifier. The purpose of this mechanism is to instantiate derived classes by their identifier at runtime.E.g. CodeGenerator* cg = CodeGenerator::New("iec"); instantiates a CodeGenerator object of the type registered by "iec". See the command-line tool compiledes.cpp for a relevant use case. Registration can be conveniently triggered by instantiation of a CodeGenerator::Registration object via the provided macro. E.g. in the source that defines the class IecCodeGenerator FAUDES_REGISTERCODEGENERATOR("iec",IecCodeGenerator); is used to register the respective class with the identifier "iec".
#define	FAUDES_REGISTERCODEGENERATOR(ftype, ctype)   static CodeGenerator::Registration<ctype> gRegister(ftype)
	Class registration macro.
