   abstract class PersonBuilder {
     static PersonBuilder builder() {
       return new AutoBuilder_PersonBuilder();
     }

     abstract PersonBuilder setName(String name);
     abstract PersonBuilder setId(int id);
     abstract Person build();
   }

Element Detail

callMethod

public abstract String callMethod

The static method from ofClass() to call when the build-method of the builder is called. By default this is empty, meaning that a constructor rather than a static method should be called. There can be more than one method with the given name, or more than one constructor, in which case the one to call is the one whose parameter names and types correspond to the abstract methods of the class or interface with the @AutoBuilder annotation.

Default:

""

ofClass

public abstract Class<?> ofClass

The class or interface containing the constructor or static method that the generated builder will eventually call. By default this is the class or interface that contains the class or interface with the @AutoBuilder annotation.

Default:

java.lang.Void.class
