Detailed Description

The Unit class.

This class provides a set of units for the framework. Use these to specify the unit of your value. In addition the class offers methods to convert floating point numbers from a specified unit to the standard unit of the framework.

//multiply with a Unit to convert to standard units, e.g.
double length = 10.0 * Unit::mm;
// length now equals 1.0 (stand for length: cm)
 
//divide with a Unit to convert from standard units to the given one:
double length_mm  = length / Unit::mm;

This class cannot be instantiated, use the static members directly. The implementation can be found in UnitConst.cc
