PolylineBuilder class final
The polyline builder allows you to create and modify Polyline geometries incrementally.
Polyline geometries are immutable and cannot be changed directly once created. The polyline builder allows you to change the contents of the shape by using the mutable MutablePartCollection that is accessible from MultipartBuilder.parts. Each MutablePart, in the collection, comprises a collection of segments that make the MutablePart. You can add or remove a MutablePart from the MutablePartCollection, or you can create a new or edit the segment vertices of an existing MutablePart. Use GeometryBuilder.toGeometry to return the new Polyline from the builder.
