TypedAggregateExpression

case class TypedAggregateExpression(aggregator: expressions.Aggregator[Any, Any, Any], inputDeserializer: Option[Expression], inputClass: Option[Class[_]], inputSchema: Option[StructType], bufferSerializer: Seq[NamedExpression], bufferDeserializer: Expression, outputSerializer: Seq[Expression], outputExternalType: DataType, dataType: DataType, nullable: Boolean) extends DeclarativeAggregate with NonSQLExpression with Product with Serializable

A helper class to hook Aggregator into the aggregation system.
