Class template absolute



// In header: <boost/units/absolute.hpp>

template<typename Y> 
class absolute {
  // types
  typedef absolute< Y > this_type; 
  typedef Y             value_type;

  // construct/copy/destruct
  absolute(const value_type &);
  absolute(const this_type &);
  this_type & operator=(const this_type &);

  // public member functions
  const value_type & value() const;
  const this_type & operator+=(const value_type &);
  const this_type & operator-=(const value_type &);


A wrapper to represent absolute units (points rather than vectors). Intended originally for temperatures, this class implements operators for absolute units so that addition of a relative unit to an absolute unit results in another absolute unit : absolute<T> +/- T -> absolute<T> and subtraction of one absolute unit from another results in a relative unit : absolute<T> - absolute<T> -> T.

absolute public construct/copy/destruct

  1. absolute();
  2. absolute(const value_type & val);
  3. absolute(const this_type & source);
  4. this_type & operator=(const this_type & source);

absolute public member functions

  1. const value_type & value() const;
  2. const this_type & operator+=(const value_type & val);
  3. const this_type & operator-=(const value_type & val);
