 /** The threading model of classes generated by {@link Model @Model} requires

  * that all operations are perform from the originating thread - unless they

  * are invoked as {@link ModelOperation @ModelOperation} methods.

  * <p>

  * A method in a class annotated by {@link Model @Model} annotation may be

  * annotated by {@link ModelOperation @ModelOperation}. The method has

  * to be static (unless {@link Model#instance() instance mode} is on), 

  * non-private and return <code>void</code>. The first parameter

  * of the method must be the {@link Model#className() model class} followed

  * by any number of additional arguments.

  * <p>

  * As a result method of the same name and the same list of additional arguments

  * (e.g. without the first model class one) will be generated into the 

  * {@link Model#className() model class}. This method can be invoked on any

  * thread, any time and it is the responsibility of model manipulating

  * technology to ensure the model is available and only then call back to 

  * the original method annotated by {@link ModelOperation @ModelOperation}.

  * The call may happen synchronously (if possible), or be delayed and invoked

  * later (on appropriate dispatch thread), without blocking the caller.

  * <pre>

  * 

  * {@link Model @Model}(className="Names", properties={

  *   {@link Property @Property}(name = "names", type=String.class, array = true)

  * })

  * static class NamesModel {

  *   {@link ModelOperation @ModelOperation} static void <b>updateNames</b>(Names model, {@link java.util.List}&lt;String;gt; arr) {

  *     <em>// can safely access the model</em>

  *     model.getNames().addAll(arr);

  *   }

  * 

  *   static void initialize() {

  *     final Names pageModel = new Names();

  *     pageModel.applyBindings();

  * 

  *     <em>// spawn to different thread</em>

  *     {@link java.util.concurrent.Executors}.newSingleThreadExecutor().execute({

  *       List&lt;String&gt; arr = <em>// ... obtain the names somewhere from network</em>

  *       pageModel.<b>updateNames</b>(arr);

  *       // returns immediately, later it invokes the model operation

  *     });
