◆ LineSegment() [1/3]

GeoLib::LineSegment::LineSegment	(	GeoLib::Point *const	a,
		GeoLib::Point *const	b,
		bool	point_mem_management_by_line_segment = false )

Constructs a line segment given by its begin and end points.

Remarks: The main purpose of class LineSegment is the use within a polyline. For this reason the memory is not managed per default. But the user has the freedom to hand over the responsibility for the mem management of the points to the object.
