    028/**
    029 * PropertyOrder is an annotation at the class level that controls the sort order of the Property annotations present
    030 * on that class.
    031 * </p>
    032 * Order.DECLARED is the default sort order in which the properties are returned in the order they are returned by the
    033 * reflection API of the JVM. This can be implementation specific and is not guaranteed to be stable.
    034 * <p/>
    035 * Using Order.ALPHABETICAL will cause the properties to be sorted alphabetically.
    036 * <p/>
    037 * Order.GIVEN and an array of Strings containing <em>all</em> properties of that class, will result in a custom order.
