創建兩個幾何的對稱差異。對稱差異包括在任一集合中的部分,但不包括在兩個集合中。
參數:
類型 說明 XOR 操作中的 Geometry 實例之一。
rightGeometry GeometryXOR 操作中的 Geometry 實例之一。
返回:
類型 說明 Promise<(Geometry|Geometry[])> 解析時,響應是兩個幾何形狀的對稱差異。 例子:
// Creates a new geometry based on the // symmetric difference of the two const geometry = await geometryEngineAsync.symmetricDifference(boundaryPolygon, buffers);
基本信息
以下是所在類或對象的基本信息。
AMD:
require(["esri/geometry/geometryEngineAsync"], (geometryEngineAsync) => { /* code goes here */ });
ESM:
import * as geometryEngineAsync from "@arcgis/core/geometry/geometryEngineAsync";
對象:
esri/geometry/geometryEngineAsync
自從:用於 JavaScript 4.0 的 ArcGIS API
