HERE Maps JS API v3:监听 `clusteringend` 事件

HERE Maps JS API v3: listen to `clusteringend` event

有没有什么方便的方法判断聚类进程是否有finished/ended?我似乎没有在 the clustering provider 中看到任何我可以收听的本地 clusteringend 事件。

自从过去几天以来,这个问题又让我头疼了。 =(

是的,随便吧。我没有等待一些 HERE 地图菜鸟的令人失望的回答,而是尝试解决我的问题并做出了一些奇怪的事情(尚未对其进行彻底测试,但到目前为止它运行良好):

var
/*
 * Work "listen-to-clusteringend-event-issue" around.
 */
processedNoisePointCounter   = 0,
incrementProcessedNoisePoint = function () {
    processedNoisePointCounter++;

    if (processedNoisePointCounter === dataPoints.length) {
        map.dispatchEvent('clusteringend');
    }
},
clusteredDataProvider        = new H.clustering.Provider([]),
defaultTheme                 = clusteredDataProvider.getTheme(),
customTheme                  = {

    /**
     *
     * @implements {H.clustering.ITheme.getClusterPresentation}
     */
    getClusterPresentation: function (cluster) {
        var clusterMarker = defaultTheme.getClusterPresentation.call(defaultTheme, cluster);

        cluster.forEachEntry(function (entry) {

            if (!entry.isCluster()) {
                incrementProcessedNoisePoint();
            }
        });

        return clusterMarker;
    },

    /**
     *
     * @implements {H.clustering.ITheme.getNoisePresentation}
     */
    getNoisePresentation: function (noisePoint) {
        var noiseMarker = defaultTheme.getNoisePresentation.call(defaultTheme, noisePoint);

        incrementProcessedNoisePoint();

        return noiseMarker;
    }
};

clusteredDataProvider.setTheme(customTheme);
clusteredDataProvider.setDataPoints(dataPoints);

var layer = new H.map.layer.ObjectLayer(clusteredDataProvider);
map.addLayer(layer);

map.addEventListener('clusteringend', function () {
    var message = 'Clustering allegedly ends. ;)';

    console.log(message);
    window.alert(message);
});
