Annotation Interface DBusProperty

@Target(TYPE) @Retention(RUNTIME) @Repeatable(DBusProperties.class) public @interface DBusProperty
Appends information about properties in the interface. The annotated properties are added to the introspection data. In case of complex type of the property please use TypeRef.

Usage: 

@DBusInterfaceName("com.example.Bar")
@DBusProperty(name = "Name", type = String.class)
@DBusProperty(name = "ListOfVariables", type = List.class, access = Access.READ)
@DBusProperty(name = "MapOfStringList", type = ComplexTypeWithMapAndList.class, access = Access.READ)
public interface Bar extends DBusInterface {

  // TypeRef allows to provide detailed information about type
  interface ComplexTypeWithMapAndList extends TypeRef<Map<String, List<String>>> {
  }
}

As an alternative to this annotation, you might consider using DBusBoundProperty. This allows you to achieve the same results with less code.
