Question

我在代码中使用PercentileAggregation。来自_plugin / head的结果：

"aggregations": {
"load_time_outlier": {
"values": {
"1.0": 35,
"1.0_as_string": "35.0",
"5.0": 35,
"5.0_as_string": "35.0",
"25.0": 35,
"25.0_as_string": "35.0",
"50.0": 35,
"50.0_as_string": "35.0",
"75.0": 35,
"75.0_as_string": "35.0",
"95.0": 36,
"95.0_as_string": "36.0",
"99.0": 36,
"99.0_as_string": "36.0"
}
}
}

通过Java客户端（TCP），我将其作为InternalPercentiles。

    Aggregations aggregations = response.getAggregations();
    if(aggregations.getAsMap().get(aggregationKey) instanceof InternalPercentiles){
    InternalPercentiles intPercentiles = 
      (InternalPercentiles) aggregations.getAsMap().get(aggregationKey);
//My logic here
}

我想在评论的地方写一个逻辑，这样我就可以得到我的结果作为地图：
密钥： load_time_outlier
值列表包含[{“1.0”：35}，{“5.0”：35}等地图。]

逻辑我试过：

Iterator<Percentile> iterator = intPercentiles.iterator();
Map<String, Object> aggregationTermsMap = new LinkedHashMap<String, Object>();
while(iterator.hasNext()){
    Percentile percentile = iterator.next();
    aggregationTermsMap.put(new Double(percentile.getPercent()).toString(), percentile.getValue());
}
aggregationTermsList.add(aggregationTermsMap);
aggregationResults.put(aggregationKey, aggregationTermsList);

请输入

得到了答案：Class Cast（（InternalPercentiles）intPercentiles）.iterator（）缺失。

Iterator<Percentile> iterator = ((InternalPercentiles)intPercentiles).iterator();
Map<String, Object> aggregationTermsMap = new LinkedHashMap<String, Object>();
while(iterator.hasNext()){
    Percentile percentile = iterator.next();
    aggregationTermsMap.put(new Double(percentile.getPercent()).toString(), percentile.getValue());
}
aggregationTermsList.add(aggregationTermsMap);
aggregationResults.put(aggregationKey, aggregationTermsList);

PercentileAggregation - 转换为HashMap
