Detailed Description

template<class JType_t>
struct JLANG::JTemplate< JType_t >

Auxiliary class for managing multiple objects.

This class can be used to replace regular base classes by corresponding data members. The various operators and methods facilitate the access to these data members.

The template value use_polymorfism in methods get and set applies to the given template parameter of these methods. If false, only exact type matches are allowed. If true, method get will return a reference to the first data member of which the type derives from the specified class and method set will assign the given value to the first data member for which a matching constructor exists.
