Detailed Description

template<class T = void>
class Arp::CommonTypeName< T >

This (meta programming) class provides the typename according the CLS (common language specification) of the as template argument passed type.

The only difference to the TypeName class is, that the resulting C++ typename contains dots instead of the C++ scope operator :: according the CLS used by .NET. The main reason is, that PLCnext provides a uniformed reflection mechanism (meta data) across multiple programming languages as C++, C#, IEC, Java, and more. All typenames of PLC data comply to the following pattern:

<LibraryNamespace>/<LocalTypeName>

where the library namespace as well as the local typename inside the library contains dot as separators but not any programming language specific operators like ::.

This class uses RTTI which must be enabled by the C++ build.

Template Parameters

T	The type to retrieve the commoon typename from.
