用于过滤特征的extent 对象。只有与范围对象相交的要素才会显示在视图中。例如,
geometryDefinition
可以设置为城市边界范围,以显示仅与此范围相交的要素。例子:
// Get the current extent of the map view and expand the extent by factor of 0.9 // Then apply this extent to stream layer's geometryDefinition. // Only features that intersect this extent will be displayed on the view. let extent = mapView.extent.clone().expand(0.9); streamLayer.geometryDefinition = extent;
