Inline converters

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

For convenience, you can inline your converter code directly into the configuration instead of providing a class reference, as shown previously.

XML (standalone and maven)
Programmatic
Gradle (Kotlin)
Gradle (Groovy)
Gradle (third party)
<configuration>
  <generator>
    <database>
      <forcedTypes>
        <forcedType>

          <!-- Specify the Java type of your custom type. This corresponds to the Converter's <U> type. -->
          <userType>java.time.Year</userType>

          <!-- Associate that custom type with your inline converter. -->
          <converter>org.jooq.Converter.ofNullable(
            Integer.class, Year.class,
            Year::of, Year::getValue
          )</converter>

          <!-- A Java regex matching fully-qualified columns, attributes, parameters. Use the pipe to separate several expressions. -->
          <includeExpression>.*\.YEAR.*</includeExpression>
        </forcedType>
      </forcedTypes>
    </database>
  </generator>
</configuration>

As always, when regular expressions are used, they are regular expressions with default flags.

The effect on your query user code will be the same as with explicit converters.

For more details about how to match columns, please refer to the section about matching columns for forced types.
