Class Segment
A class representing an edge of a multipart geometry, connecting a start to an end point.
Namespace: Esri.ArcGISRuntime.Geometry
Assembly: Esri.ArcGISRuntime.dll
Syntax
public abstract class SegmentRemarks
A segment describes a continuous line between a start location and an end location. The ArcGIS Platform, including ArcGIS Maps SDK for .NET, supports both linear segments (represented by LineSegment) and curve segments (represented by CubicBezierSegment and EllipticArcSegment).
Densify(Geometry, Double) can translate curve segments into multiple LineSegment instances to approximate the curve.
Every Part 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. Multipart geometries can be composed from and decomposed into their constituent segments if required.
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 map points in a part. As a result, when iterating through the map points in a part of a Polyline, there is one more MapPoint than the number of segments in that same part.
Segments are immutable so you can not change a segment's shape once it is created. For workflows that involve geometry editing, create a new segment with the properties you require.
Segments are used as the building blocks of the parts of Polygon and Polyline classes.
From v100.12, curve segments are supported in geometry editing workflows. You can add curve segments
to a MultipartBuilder<T>, and if a geometry has curves (HasCurves
is true) then curve segments are returned where applicable from the collections that
comprise the multipart geometry. Curve and linear segments can be mixed together in the same geometry.
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 |
| StartPoint | Gets the start point of the segment. |
Methods
| Name | Description |
|---|---|
| IsEqual(Segment) | Checks if two segments and their spatial references are equal. |
