Templates in C++

cpp templates

template <class I, class v> class Lattice 
{
// private and public code here.
// constructors, building a lattice, navigating.
}

template <class Type= double> class Range 
{
// default type is double. 

private:
    Type lo:
    Type: hi;
    Range(); // constructor

public:
Range(const Type& low, const Type& high);
Range(const Range<Type>& ran2);

virtual ~Range();

// modifier functions.
// setters
void low(const Type& t1);
void high(const Type& t1);

// getters 
Type low() const;
Type high() const;

Type length() const;



bool left(const Type& value) const;
bool right(const Type& value) const;
bool contains(const Type& value) const;

Range<Type>& operator = (const Range<Type>& ran2);


}

Using the template class.

A template class is a type. In constrast to non-templated classes, it has no instances as such.
