Syntax

public abstract class Segment

Remarks

A segment describes a continuous line between a start location and an end location. Every ReadOnlyPart in a Multipart geometry is a collection of Segment instances, where the end of one segment is at exactly the same location as the start of the following segment.

Because a single location is shared by adjacent segments, a single MapPoint object is used to represent the shared location when you iterate through the points in a part (Points). As a result, when iterating through the points in a part of a polyline or polygon, there is one more point than the number of segments in that same part.

Segments are immutable so you cannot change a segment's shape once it is created. For workflows that involve geometry editing, create a new segment with the properties you require.

Both linear segments (represented by LineSegment) and curve segments (represented by CubicBezierSegment or EllipticArcSegment) are supported. Curve and linear segments can be mixed together in the same geometry. Densify(Geometry, Double) can be used to produce a polygon or polyline without curves (HasCurves = false) from one that does have curves, by translating curve segments into multiple LineSegment instances to approximate the curve.

Properties

Name	Description
EndPoint	Gets the end point of the segment.
IsClosed	Gets a value indicating whether the segment is closed (has a matching start and end point).
IsCurve	Gets a value indicating whether this segment is a curve, or a line segment.
SpatialReference	Gets the spatial reference for the segment, or null if the segment does not have a spatial reference.
StartPoint	Gets the start point of the segment.

Methods

Name	Description
IsEqual(Segment)	Checks if two segments and their spatial references are equal.
