double CoordinateType
Coordinate type.
Definition: DPosition.h:33
void clear()
Set all dimensions to zero.
Definition: DPosition.h:339
Maintain an average position by summing up positions with weights.
Definition: AveragePosition.h:31
AveragePosition()
Default constructor.
Definition: AveragePosition.h:49
PositionType const & getPosition() const
Returns the current average position.
