Usage

From source file:DynaBeansExampleV1.java

private static Object createMovieBean() throws Exception {

    // first create the properties
    DynaProperty properties[] = new DynaProperty[] { new DynaProperty("title", String.class),
            new DynaProperty("dateOfRelease", Date.class), new DynaProperty("keywords", String[].class),
            new DynaProperty("genre", Map.class), new DynaProperty("actors", List.class),
            new DynaProperty("director", DynaBean.class) };

    // next using the properties define the class
    DynaClass movieClass = new BasicDynaClass("movie", null, properties);

    // now, with the class, create a new instance
    DynaBean movieBean = movieClass.newInstance();

    // set its properties
    movieBean.set("title", "The Italian Job");
    movieBean.set("dateOfRelease", new GregorianCalendar(1969, 0, 1).getTime());
    movieBean.set("keywords", new String[] { "Italy", "Bank Robbery" });

    Map genre = new HashMap();
    genre.put("THR", "Thriller");

    movieBean.set("genre", genre);
