Annotation Interface Role

@Target({FIELD,METHOD})
@Retention(RUNTIME)
@WriteAccess(MANUAL)
@Documented
public @interface Role

Designates this field as a role field. A role is the name of the field of the owner, where this object is referenced.

 @DSL
  class Database {
      @Role User ddl
      @Role User dml
      @Role User monitoring
  }

  @DSL
  class User {
    @Key String name
    @Owner Database database
    @Role String role
  }

 when:
 instance = Database.Create.With {
     ddl("user1")
     dml("user2")
     monitoring("user3")
 }

 then:
 instance.ddl.role == "ddl"
 instance.dml.role == "dml"
 instance.monitoring.role == "monitoring"
 

Note that while it is technically valid to use Role without a matching Owner field, the role will always be null, so this usually only makes sense in special, inheritance related cases.
