A polyline (under construction)


Add_Point This function has 2 overloads.
Add_Segment Appends the the givin line segment to the end of the polyline. We assume that if the first point in the segment is the same as the endpoint of the polygon, we don't need to add the first point.
Constructor This function has 2 overloads.
Insert_Point This function has 2 overloads.
Insert_Segment Inserts a segment into a polyline. This will check the points of the segment and only add the points if they are not identical to what will become the adjacent points.
Invalidate Many properties are derived from the points. Generally, these are calculated once and cached. Most changes that can be made externally will automatically cause an invalidation to occur, so adding points, for instance, will force the perimeter to be recalculated. This forces such an invalidation so that the next time derived properties are queried, they will be recalculated.
mwShape_To_PolyLines If a Shape has multiple parts, this will create a separate polyline for each part.
PolyLines_To_mwShape Converts a list of polylines into a single multi-part shape
SegmentsWithin Returns a list of segments from the Polyline that are within the submitted extents.
SegmentsWithinDistanceOf Creates a list of segments from this polyline that are within the specified distance to a point
ToSegments Will create a list of segment objects for the entire polygon
