Annotation Type SuperBuilder

@Target(TYPE) @Retention(SOURCE) public @interface SuperBuilder
The SuperBuilder annotation creates a so-called 'builder' aspect to the class that is annotated with @SuperBuilder, but which works well when extending. It is similar to @Builder, except it is only legal on types, is less configurable, but allows you to extends other builder-able classes.

All classes in the hierarchy must be annotated with @SuperBuilder.

Lombok generates 2 inner 'builder' classes, which extend the parent class' builder class (unless your class doesn't have an extends clause). Lombok also generates a static method named builder(), and a protected constructor that takes 1 argument of the builderclass type.

The TBuilder class contains 1 method for each parameter of the annotated constructor / method (each field, when annotating a class), which returns the builder itself. The builder also has a build() method which returns a completed instance of the original type.

Complete documentation is found at the project lombok features page for @SuperBuilder.

    • builderMethodName

      String builderMethodName
      Returns:
      Name of the method that creates a new builder instance. Default: builder. If the empty string, suppress generating the builder method.
      Default:
      "builder"

    • buildMethodName

      String buildMethodName
      Returns:
      Name of the method in the builder class that creates an instance of your @Builder-annotated class.
      Default:
      "build"

    • toBuilder

      boolean toBuilder
      If true, generate an instance method to obtain a builder that is initialized with the values of this instance. In this case, all superclasses must also have toBuilder=true.
      Returns:
      Whether to generate a toBuilder() method.
      Default:
      false

    • setterPrefix

      String setterPrefix
      Prefix to prepend to 'set' methods in the generated builder class. By default, generated methods do not include a prefix. For example, a method normally generated as someField(String someField) would instead be generated as withSomeField(String someField) if using @SuperBuilder(setterPrefix = "with"). Note that using "with" to prefix builder setter methods is strongly discouraged as "with" normally suggests immutable data structures, and builders by definition are mutable objects. For @Singular fields, the generated methods are called withName, withNames, and clearNames, instead of the default name, names, and clearNames. This prefix only applies to the 'set' methods for the fields of the annotated class. For consistency reasons, you should use the same prefix on all superclasses and subclasses that use @SuperBuilder.
      Returns:
      The prefix to prepend to generated method names.
      Default:
      ""
