/**
* <p>
* Describes the interface of a management bean. This allows
* the user to access the bean dynamically, without knowing
* the details of any of its attributes, operations,
* constructors or notifications beforehand. The information
* is immutable as standard. Of course, subclasses may change
* this, but this behaviour is not recommended.
* </p>
* <p>
* The contents of this class, for standard management beans,
* are dynamically compiled using reflection.
* {@link #getClassName()} and {@link #getConstructors()}
* return the name of the class and its constructors, respectively.
* This is much the same as could be obtained by reflection on the
* bean. {@link #getAttributes()} and {@link #getOperations()},
* however, do something more in splitting the methods of the
* class into two sets. Those of the form, <code>getXXX</code>,
* <code>setXXX</code> and <code>isXXX</code> are taken to be
* the accessors and mutators of a series of attributes, with
* <code>XXX</code> being the attribute name. These are returned
* by {@link getAttributes()} and the {@link Attribute} class can
* be used to manipulate them. The remaining methods are classified
* as operations and returned by {@link getOperations()}.
* </p>
* <p>
* Beans can also broadcast notifications. If the bean provides this
* facility, by implementing the {@link NotificationBroadcaster}
* interface, then an array of {@link MBeanNotificationInfo} objects
* may be obtained from {@link #getNotifications()}, which describe
* the notifications emitted.
* </p>
* <p>
* Model management beans and open management beans also supply an
* instance of this class, as part of implementing the
* {@link DynamicMBean#getMBeanInfo()} method of {@link DynamicMBean}.
* </p>
