### Abstract Value Members

1.  abstract def endPartition(): Iterable[Row]

   This method can be used to generate output rows that are based on any state information aggregated in process().

   This method can be used to generate output rows that are based on any state information aggregated in process(). This method is invoked once for each partition, after all rows in that partition have been passed to process().

   The rows returned in this method must match the StructType defined in outputSchema

   Since: 1.2.0

   Definition Classes
     UDTF
2.  abstract def outputSchema(): StructType

   A StructType that describes the data types of the fields in the rows returned by the process() and endPartition() methods.

   A StructType that describes the data types of the fields in the rows returned by the process() and endPartition() methods.

   For example, if a UDTF returns rows that contain a StringType and IntegerType field, the outputSchema() method should construct and return the following StructType object: {{ override def outputSchema(): StructType = StructType(StructField("word", StringType), StructField("count", IntegerType)) }}

   This method is invoked once for each row in the input partition. The arguments passed to the registered UDTF are passed to process().

   The rows returned in this method must match the StructType defined in outputSchema
