### Abstract Value Members

1.  abstract def outputType(): DataType

   A DataType that describes the type of the value returned by the terminate() method.

   A DataType that describes the type of the value returned by the terminate() method.

   For example, if a UDAF returns an integer value, outputType() should return IntegerType: {{ override def outputType(): DataType = IntegerType }}

   returns

     A DataType describing the output type.
