# UnnestFrame 類別
<a name="aws-glue-api-crawler-pyspark-transforms-UnnestFrame"></a>

對 `DynamicFrame` 解除巢狀化，將巢狀化物件壓平合併為頂層元素，並且為陣列物件產生聯結鍵。

## 範例
<a name="pyspark-UnnestFrame-example"></a>

我們建議您使用 [`DynamicFrame.unnest()`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#aws-glue-api-crawler-pyspark-extensions-dynamic-frame-unnest) 方法在 `DynamicFrame` 中壓平合併巢狀化結構。若要檢視程式碼範例，請參閱 [範例：使用 unnest 將巢狀化欄位轉換為頂層欄位](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#pyspark-unnest-example)。

## \_\_call\_\_(frame, transformation\_ctx = "", info="", stageThreshold=0, totalThreshold=0)
<a name="aws-glue-api-crawler-pyspark-transforms-UnnestFrame-__call__"></a>

對 `DynamicFrame` 解除巢狀化，將巢狀化物件壓平合併為頂層元素，並且為陣列物件產生聯結鍵。
+ `frame` – 欲解巢狀的 `DynamicFrame` (必要)。
+ `transformation_ctx` – 用於識別狀態資訊的唯一字串 (選用)。
+ `info` – 與轉換中的錯誤相關的字串 (選用)。
+ `stageThreshold` – 在錯誤輸出之前，轉換作業中可發生錯誤的次數上限 (選用)。預設為零。
+ `totalThreshold` – 在處理錯誤輸出之前，整體作業可發生錯誤的次數上限 (選用)。預設為零。
