Class UserDefinedFunction

java.lang.Object

com.google.cloud.bigquery.UserDefinedFunction

All Implemented Interfaces:

Serializable

public abstract class UserDefinedFunction
extends Object
implements Serializable

Google BigQuery User Defined Function. BigQuery supports user-defined functions (UDFs) written in JavaScript. A UDF is similar to the "Map" function in a MapReduce: it takes a single row as input and produces zero or more rows as output. The output can potentially have a different schema than the input.
