NamedUserDefinedFunction13

class NamedUserDefinedFunction13<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, R>(    val name: String,     udf: UserDefinedFunction,     encoder: Encoder<R>) : UserDefinedFunction13<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, R> , NamedUserDefinedFunction<R, NamedUserDefinedFunction13<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, R>>

Instance of a UDF with 13 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.
