A segment represents an edge of a multipart geometry, connecting a start to an end point. A segment describes a continuous line between a start location and an end location. The ArcGIS Platform, including this API, supports both linear segments (represented by LineSegment) and curve segments (represented by CubicBezierSegment and EllipticArcSegment).
GeometryEngine.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 Point object is used to represent the shared location when you iterate through the points in a part. 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 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.
From v100.12, curve segments are supported in geometry editing workflows. You can add curve segments to a MultipartBuilder, and if a geometry has curves (Geometry.getHasCurves() is true) then curve segments are returned where applicable from the Part collections that comprise the multipart geometry. Curve and linear segments can be mixed together in the same geometry.
False if the object is a LineSegment; true otherwise. Prior to v100.12, only LineSegment instances were supported when creating new geometries using a MultipartBuilder or iterating the Segment instances in an existing Multipart geometry.
