# UserDefinedFunction

###

#### case class UserDefinedFunction extends Product with Serializable

Encapsulates a user defined lambda or function that is returned by UDFRegistration.registerTemporary or by com.snowflake.snowpark.functions.udf.

Use UserDefinedFunction.apply to generate Column expressions from an instance.

    import com.snowflake.snowpark.functions._
    val myUdf = udf((x: Int, y: String) => y + x)
    df.select(myUdf(col("i"), col("s")))
