/**
 * This class may be extended to create a custom TileLayer. It is a generic tile layer class designed to work with various tile sources,
 * not just ArcGIS cached [map services](https://doc.esri.com/en/arcgis-enterprise/latest/administer/what-is-a-map-service.html),
 * which are specifically handled by the [TileLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/TileLayer/) class. Tile layers are composed of images, such as satellite imagery,
 * that are composed of square tiles mosaicked together in columns and rows, giving the layer the appearance that it is one continuous image.
 * They have several levels of detail (LOD) that permit users to zoom in to any region of the map and load additional tiles that depict features
 * in higher resolution at larger map scales.
 *
 * Tile layers often provide geographic context for other layers such as
 * [FeatureLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/FeatureLayer/) and tend to perform better than other layers,
 * such as [MapImageLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/MapImageLayer/) and [ImageryLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/ImageryLayer/),
 * that request and display a single image per view.
 *
 * You can create a custom tile layer by calling [Accessor.createSubclass()](https://developers.arcgis.com/javascript/latest/references/core/core/Accessor/#createSubclass)
 * on the `BaseTileLayer` class. You may create a custom tile layer for one of the following reasons:
 *
 * * The source of the images isn't explicitly supported by the ArcGIS Maps SDK for JavaScript
 * * Images need to be preprocessed prior to display in the view
 *
 * ### Setting up a custom tile layer
 * Unlike TileLayer, the BaseTileLayer does not make assumptions about the type of data it retrieves, making it more flexible and capable of working
 * with a wider variety of tile sources. By default, the BaseTileLayer is configured to use the Web Mercator spatial reference.
 * If a custom tile source does not use the Web Mercator spatial reference, the BaseTileLayer must be explicitly configured with three key properties
 * in its constructor to ensure proper alignment with the source. Those properties are [tileInfo](https://developers.arcgis.com/javascript/latest/references/core/layers/BaseTileLayer/#tileInfo), [spatialReference](https://developers.arcgis.com/javascript/latest/references/core/layers/BaseTileLayer/#spatialReference),
 * and [fullExtent](https://developers.arcgis.com/javascript/latest/references/core/layers/BaseTileLayer/#fullExtent).
 *
 * ```js
 * // set the spatial reference to New Zealand Transverse Mercator
 *  const spatialReference = new SpatialReference({
 *    wkid: 2193
 * });
 *
 * // create the origin point for the tileInfo
 * // The upper left corner of the tiling scheme,
 * const origin = new Point({
 *   x: -4020900,
 *   y: 19998100,
 *   spatialReference
 * });
 *
 * // Create LODs based on the source tiles
 * const tileInfo = new TileInfo({
 *   spatialReference,
 *   origin: origin,
 *   format: "mixed",
 *   lods: [{
 *      "level": 0,
 *      "resolution": 156543.03392799935,
 *      "scale": 591657527.591552
 *     },
 *     {
 *        "level": 1,
 *        "resolution": 78271.51696399967,
 *        "scale": 295828763.795776
 *      },
 *      // other LODs
 *    ]
 *  });
 *
 * const MyCustomTileLayer = BaseTileLayer.createSubclass({
 *   constructor() {
 *     this.tileInfo = tileInfo;
 *     this.spatialReference = spatialReference;
 *     this.fullExtent = new Extent ({
 *       xmin: -1497310.4689000002,
 *       ymin: 3678220.3271,
 *       xmax: 4749968.6755,
 *       ymax: 7192314.8459,
 *        spatialReference
 *     })
 *    },
 *    // properties of the custom tile layer
 *    properties: {
 *      urlTemplate: null,
 *    }
 * });
 * ```
 *
 * ### Request images as they are defined
 *
 * To request images as they are predefined from a data source, overwrite the [getTileUrl()](https://developers.arcgis.com/javascript/latest/references/core/layers/BaseTileLayer/#getTileUrl)
 * method so it returns the URL for the requested tile for a given level, row and column.
 *
 * ```js
 * // override getTileUrl()
 * // generate the tile url for a given level, row and column
 * getTileUrl: function (level, row, col) {
 *   return this.urlTemplate.replace("{z}", level).replace("{x}", col).replace("{y}", row);
 * }
 * ```
 *
 * ### Preprocess images prior to display
 *
 * If data needs to be preprocessed prior to display, then override the [fetchTile()](https://developers.arcgis.com/javascript/latest/references/core/layers/BaseTileLayer/#fetchTile)
 * method. For example, if you need to apply a
 * [compositing operation](https://developer.mozilla.org/docs/Web/API/CanvasRenderingContext2D/globalCompositeOperation)
 * to the image returned from the server before the image is displayed then you would override this method.
 *
 * ```js
 * // override fetchTile() method to process the data returned
 * // from the server.
 * fetchTile: function (level, row, col, options) {
 *   // call getTileUrl method to construct the Url for the image
 *   // for given level, row and column
 *   let url = this.getTileUrl(level, row, col);
 *
 *   // request for the tile based on the url returned from getTileUrl() method.
 *   // the signal option ensures that obsolete requests are aborted.
 *   return esriRequest(url, {
 *     responseType: "image",
 *     signal: options && options.signal
 *   })
 *   .then(function (response) {
 *     // when esriRequest resolves successfully,
 *     // process the image that is returned
 *     let image = response.data;
 *     let width = this.tileInfo.size[0];
 *     let height = this.tileInfo.size[0];
 *
 *     // create a canvas with a filled rectangle
 *     let canvas = document.createElement("canvas");
 *     let context = canvas.getContext("2d");
 *     canvas.width = width;
 *     canvas.height = height;
 *
 *     // Apply the color provided by the layer to the fill rectangle
 *     if (this.tint) {
 *       context.fillStyle = this.tint.toCss();
 *       context.fillRect(0, 0, width, height);
 *       // apply multiply blend mode to canvas' fill color and the tile
 *       // returned from the server to darken the tile
 *       context.globalCompositeOperation = "multiply";
 *     }
 *     context.drawImage(image, 0, 0, width, height);
 *     return canvas;
 *   }.bind(this));
 * }
 * ```
 *
 * See the following samples for examples of how this works:
 *
 * * [Sample - Custom TileLayer](https://developers.arcgis.com/javascript/latest/sample-code/layers-custom-tilelayer/)
 * * [Sample - Custom LERC Layer](https://developers.arcgis.com/javascript/latest/sample-code/layers-custom-lerc-2d/)
 * * [Sample - Custom BlendLayer](https://developers.arcgis.com/javascript/latest/sample-code/layers-custom-blendlayer/)
 *
 * If the custom tile layer requires loadable resources, then you must load all loadable
 * dependencies on the layer, within the [load()](https://developers.arcgis.com/javascript/latest/references/core/layers/BaseTileLayer/#load) method. Add the promise returned
 * from the loadable resource with the [addResolvingPromise()](https://developers.arcgis.com/javascript/latest/references/core/layers/BaseTileLayer/#addResolvingPromise) method.
 * The layer will then wait for all of dependencies to
 * finish loading before it is considered [loaded](https://developers.arcgis.com/javascript/latest/references/core/layers/BaseTileLayer/#loaded).
 *
 * ```js
 * // Override load method
 * load: function () {
 *  // multiply property is an array of ArcGIS cached map services
 *  this.multiply.forEach(function (layer) {
 *    // loop through each tile layers and call
 *    // load method on each layer
 *    let promise = layer.load();
 *
 *    // add the promise of each load() method to addResolvingPromise()
 *    // the custom tile layer will be loaded when every promise is resolved
 *    this.addResolvingPromise(promise);
 *  }, this);
 * }
 * ```
 * The layer is responsible for generating the tile URL and fetching tiles from the server for the
 * level, row, and column provided by the [LayerView](https://developers.arcgis.com/javascript/latest/references/core/views/layers/LayerView/). The
 * LayerView displays the fetched tiles.
