NamedUserDefinedFunction12

class NamedUserDefinedFunction12<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, R>(val name: String, udf: UserDefinedFunction, encoder: Encoder<R>) : UserDefinedFunction12<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, R> , NamedUserDefinedFunction<R, NamedUserDefinedFunction12<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, R>>

Instance of a UDF with 12 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.
