pointCloudRenderers

在使用TypeScript开发时，用于导入PointCloudRenderer类的便利模块。例如，而不是像这样一次导入一个渲染器:

import PointCloudClassBreaksRenderer = require("esri/renderers/PointCloudClassBreaksRenderer");
import PointCloudRGBRenderer = require("esri/renderers/PointCloudRGBRenderer");
import PointCloudStretchRenderer = require("esri/renderers/PointCloudStretchRenderer");
import PointCloudUniqueValueRenderer = require("esri/renderers/PointCloudUniqueValueRenderer");

您可以使用此模块在单行上导入它们:

import {
  PointCloudClassBreaksRenderer,
  PointCloudRGBRenderer,
  PointCloudStretchRenderer,
  PointCloudUniqueValueRenderer
} from "esri/pointCloudRenderers";

此模块还允许您在呈现器上实现类型保护，使代码更加智能。

import { PointCloudRenderer } from "esri/pointCloudRenderers";

function logInfos(renderer: PointCloudRenderer): void {
  if (renderer.type === "point-cloud-class-breaks") {
    // 新版本4.8中，编译器知道呈现器是PointCloudClassBreaksRenderer
    console.log("renderer colorClassBreakInfos: ", renderer.colorClassBreakInfos);
  }
}
