Detailed Description

C2DLineBase class, an abstract class which defines the functionality that a Line class must have.

C2DLineBase class, an abstract class which defines the functionality that a Line class must have (in addition to that in C2DBase) to be a line. Lines that inherit properly from this can be used in the C2DPolyBase class to form a closed area / shape with all the associated functions such as distance and intersections.

Member Function Documentation

virtual void C2DLineBase::GetSubLines (  const C2DPointSet &  PtsOnLine, C2DLineBaseSet &  LineSet )  const [pure virtual]

Given a set of points on the line, this function creates sub lines defined by those points. Required by intersection, union and difference functions in the C2DPolyBase class. Implemented in C2DArc, and C2DLine.
