Example 1 with UdfSchemaProvider

use of io.confluent.ksql.function.udf.UdfSchemaProvider in project ksql by confluentinc.

the class Round method provideDecimalSchemaWithDecimalPlaces.

// Invoked via reflection
@SuppressWarnings("unused")
@UdfSchemaProvider
public static SqlType provideDecimalSchemaWithDecimalPlaces(final List<SqlArgument> params) {
    final SqlType s0 = params.get(0).getSqlTypeOrThrow();
    if (s0.baseType() != SqlBaseType.DECIMAL) {
        throw new KsqlException("The schema provider method for round expects a BigDecimal parameter" + "type as first parameter.");
    }
    final SqlType s1 = params.get(1).getSqlTypeOrThrow();
    if (s1.baseType() != SqlBaseType.INTEGER) {
        throw new KsqlException("The schema provider method for round expects an Integer parameter" + "type as second parameter.");
    }
    // the scale of the return type. See https://github.com/confluentinc/ksql/issues/6235.
    return s0;
}
