<a name="aws-glue-api-crawler-pyspark-transforms-MapToCollection-__call__"></a>

对指定 `DynamicFrameCollection` 中的每个 `DynamicFrame` 应用转换函数。
+ `dfc` – 要对其应用转换函数的原始 `DynamicFrameCollection` (必需)。
+ `callable` – 要应用于集合的每个成员的可调用转换函数 (必需)。
+ `transformation_ctx` – 用于标识状态信息的唯一字符串 (可选)。

通过将返回新 `DynamicFrameCollection` 创建的每个转换 `DynamicFrame` 在源 `DynamicFrameCollection`。
