symbol是一种基本数据类型 (primitive data type)。Symbol()函数会返回symbol类型的值,该类型具有静态属性和静态方法。它的静态属性会暴露几个内建的成员对象;它的静态方法会暴露全局的symbol注册,且类似于内建对象类,但作为构造函数来说它并不完整,因为它不支持语法:"new Symbol()"。
If working with data in aSceneView, use the following table as a guide when selecting a symbol type. Geometry typeValid symbol types PointPointSymbol3D,LabelSymbol3D,WebStyleSymbol,CIMSymbol PolylineLineSymbol3D,LabelSymbol3D PolygonPolygonSymbol3D,LabelSymbol3D ...
All 3D symbols must be used in a SceneView instance; there is no support for 3D rendering in MapViews. There are five types of 3D symbols. Four of them correspond with a different feature geometry type. The fifth, LabelSymbol3D, may be applied to any geometry type. See the table below...
