CoordinateType const &: x:

CoordinateType const &: y:

Member Function(s)

Function	Description	Parameters
CoordinateType const & x()	Get x-value.
CoordinateType const & y()	Get y-value.

Notes

	Note
	Coordinates are not initialized. If the constructor with parameters is not called and points are not assigned using `set` or `assign` then the coordinate values will contain garbage
