NamedUserDefinedFunction6

class NamedUserDefinedFunction6<T1, T2, T3, T4, T5, T6, R>(    val name: String,     udf: UserDefinedFunction,     encoder: Encoder<R>) : UserDefinedFunction6<T1, T2, T3, T4, T5, T6, R> , NamedUserDefinedFunction<R, NamedUserDefinedFunction6<T1, T2, T3, T4, T5, T6, R>>

Instance of a UDF with 6 arguments with name. This UDF can be invoked with (typed) columns in a Dataset.select or selectTyped call. Alternatively it can be registered for SQL calls using register.
