### Abstract Value Members

1.  abstract def accumulate(state: S, arg0: A0, arg1: A1, arg2: A2, arg3: A3, arg4: A4, arg5: A5): S

   Updates the aggregation state with a new input row.

   Updates the aggregation state with a new input row.

   state

     The current aggregation state.

   arg0

     The input value for argument 1.

   arg1

     The input value for argument 2.

   arg2

     The input value for argument 3.

   arg3

     The input value for argument 4.

   arg4

     The input value for argument 5.

   arg5

     The input value for argument 6.

   returns

     The updated aggregation state.

   Since

     1.19.0

2.  abstract def initialize(): S

   returns

     The initial state of the aggregation.

   Since

     1.19.0

3.  abstract def merge(state1: S, state2: S): S

   Merges two aggregation states into one.

   Merges two aggregation states into one.

   state1

     The first aggregation state.

   state2

     The second aggregation state.

   returns

     The merged aggregation state.

   Since

     1.19.0

4.  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.
