Annotation Type Model

@Retention(RUNTIME) @Target(METHOD) @Incubating public @interface Model
Denotes that the RuleSource method rule carrying this annotation creates a new top level element in the model space.

The method must advertise a name and type for the model element. The name is defined either by the name of the method, or the value() of this annotation. The type is defined differently depending on whether the new element is Managed or not.

Creating managed model elements

If the element is to be of a managed type, the method must return void and receive the newly created instance as the first parameter. All other parameters are considered inputs.

It is an error for a @Model rule to return void and specify a non-managed type as the first parameter. It is an error for a @Model rule to return void and for the first parameter to be annotated with Path. It is an error for a @Model rule to specify a managed type as the return type.

Creating non-managed model elements

If the element is to be of a non-managed type, the method must return the newly created instance. All parameters are considered inputs. Please see RuleSource for more information on method rules.
