Detailed Description

template<class JFirst_t, class JSecond_t = JNullType>
struct JLANG::JComparable< JFirst_t, JSecond_t >

Template definition of auxiliary base class for comparison of data structures.

Specialisation of class JComparable for two data types.

The various specialisations of this class implement the operators < > <= >= == != .

The first template parameter should have the corresponding member methods: 

      bool less(const JSecond_t&) const;
      bool more(const JSecond_t&) const;

where JFirst_t andd JSecond_t refers to the first and second template parameter, respectively. The second template parameter may be a primitive data type. This class uses in-class friend operators (see Barton-Nackman trick).
