用於過濾特征的extent 對象。隻有與範圍對象相交的要素才會顯示在視圖中。例如,
geometryDefinition
可以設置為城市邊界範圍,以顯示僅與此範圍相交的要素。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;
