+/**
+ * Java bean wrapper class.
+ *
+ *
+ * <h6 class='topic'>Description</h6>
+ * <p>
+ * A wrapper that wraps Java bean instances inside of a {@link Map} interface that allows
+ * properties on the wrapped object can be accessed using the {@link Map#get(Object) get()} and {@link Map#put(Object,Object) put()} methods.
+ * <p>
+ * Use the {@link BeanContext} class to create instances of this class.
+ *
+ *
+ * <h6 class='topic'>Bean property order</h6>
+ * <p>
+ * The order of the properties returned by the {@link Map#keySet() keySet()} and {@link Map#entrySet() entrySet()} methods are as follows:
+ * <ul class='spaced-list'>
+ * <li>If {@link Bean @Bean} annotation is specified on class, then the order is the same as the list of properties in the annotation.
+ * <li>If {@link Bean @Bean} annotation is not specified on the class, then the order is the same as that returned
+ * by the {@link java.beans.BeanInfo} class (i.e. ordered by definition in the class).
+ * </ul>
+ * <br>
+ * The order can also be overridden through the use of a {@link BeanTransform}.
+ *
+ *
+ * <h6 class='topic'>POJO transforms</h6>
+ * <p>
+ * If {@link PojoTransform PojoTransforms} are defined on the class types of the properties of this bean or the bean properties themselves, the
+ * {@link #get(Object)} and {@link #put(String, Object)} methods will automatically
+ * transform the property value to and from the serialized form.

+ * Encapsulates all access to the properties of a bean class (like a souped-up {@link java.beans.BeanInfo}).
+ *
+ *
+ * <h6 class='topic'>Description</h6>
+ * <p>
+ * Uses introspection to find all the properties associated with this class. If the {@link Bean @Bean} annotation
+ * is present on the class, or the class has a {@link BeanTransform} registered with it in the bean context,
+ * then that information is used to determine the properties on the class.
+ * Otherwise, the {@code BeanInfo} functionality in Java is used to determine the properties on the class.
+ *
+ *
+ * <h6 class='topic'>Bean property ordering</h6>
+ * <p>
+ * The order of the properties are as follows:
+ * <ul class='spaced-list'>
+ * <li>If {@link Bean @Bean} annotation is specified on class, then the order is the same as the list of properties in the annotation.
+ * <li>If {@link Bean @Bean} annotation is not specified on the class, then the order is based on the following.
+ * <ul>
+ * <li>Public fields (same order as {@code Class.getFields()}).
+ * <li>Properties returned by {@code BeanInfo.getPropertyDescriptors()}.
+ * <li>Non-standard getters/setters with {@link BeanProperty @BeanProperty} annotation defined on them.
+ * </ul>
+ * </ul>
+ * <br>
+ * The order can also be overridden through the use of an {@link BeanTransform}.
+ *
+ *
+ * @param <T> The class type that this metadata applies to.
