 * JXPathBeanInfo  is similar to java.beans.BeanInfo in that it describes
 * properties of a JavaBean class.  By default, JXPathBeanInfo classes are
 * automatically generated by {@link JXPathIntrospector JXPathIntrospector}
 * based on the java.beans.BeanInfo. As with JavaBeans, the user can supply an
 * alternative implementation of JXPathBeanInfo for a custom class.  The
 * alternative implementation is located by class name, which is the same as the
 * name of the class it represents with the suffix "XBeanInfo".  So, for
 * example, if you need to provide an alternative JXPathBeanInfo class for class
 * "", write a class "" and make it implement the
 * JXPathBeanInfo interface.

     * Returns true if objects of this class are treated as atomic
     * objects which have no properties of their own.
     * For example, java.lang.String and java.lang.Number are atomic.
    boolean isAtomic();

     * Returns true if the objects of this class have dynamic properties
     * (e.g. java.util.Map). If this method returns true, getPropertyDescriptors
     * should return null and getDynamicPropertyHandlerClass should return
     * a valid class name.  An object cannot have both static and dynamic
     * properties at the same time.
    boolean isDynamic();

     * Returns a list of property descriptors for the beans described by this
     * bean info object.  Returns null for atomic beans.
    PropertyDescriptor[] getPropertyDescriptors();

     * Returns a PropertyDescriptor for the specified name or null if there
     * is no such property.
    PropertyDescriptor getPropertyDescriptor(String propertyName);

     * For dynamic objects, returns the class implementing
     * the DynamicPropertyHandler interface. That class can
     * be used to access dynamic properties.
    Class getDynamicPropertyHandlerClass();
