MultilayerPolylineSymbol class final
A polyline symbol built with multiple layers of symbols to display graphics and features that have polyline geometry.
A MultilayerPolylineSymbol can contain multiple layers that are combined to create different appearances, for example, a solid road with dashed pattern on top to show the center line. The individual layers have their own properties such as width and dash patterns, and can be accessed programmatically through MultilayerSymbol.symbolLayers. For more information about multilayer symbols, refer to Symbol layers.
If you create a MultilayerPolylineSymbol from a collection of SymbolLayer objects, the first symbol layer in the collection will be drawn first, with the second symbol layer on top of the first, and so on. Note that symbol layers in a multilayer symbol are in reverse order of how they appear in the JSON representation.
