    Detailed Description

    Polyline geometries represent the shape and location of linear features, such as a street in a road network, a contour line representing an elevation value, or a hiking trail. A Polyline can be used to define geometry for features and graphics, or as input or output for tasks or geoprocessing operations, such as the output of a network trace.

    A Polyline is composed of a series of connected Segments, where each segment defines a continuous line between a start and an end point. You can define a new Polyline from a collection of Point to create a series of straight LineSegment connecting the points you specified. You can use PolylineBuilder to build a Polyline, one point at a time, or to modify an existing Polyline.

    Additionally, Polyline can have multiple parts. Each part is a series of connected segments, but the parts can be disjoint from each other. For example, a Polyline representing a street that ends and then starts again a block later. Parts can also intersect at one or more vertices. For example, in a Polyline representing a river and its tributaries. The Polyline class inherits from Multipart, which provides members for iterating the segments and points of each part in a Polyline.

    Polyline is immutable. Instead of changing the properties of an existing Polyline, you can create new Polyline instances, or use PolylineBuilder.
