Gets the number of line segments in the collection.

virtual int GetCount() const

Return value

Returns the number of line segments in the collection.

Gets the specified line segment from the collection.

virtual int GetLineSegement(int index, CLineSegment* line) const

Parameters

[in] index The index of the line segment to retrieve.
