/**
* This class represents the meta data for ModelMBeans. Descriptors have been
* added on the meta data objects.
* <P>
* Java resources wishing to be manageable instantiate the ModelMBean using the
* MBeanServer's createMBean method. The resource then sets the ModelMBeanInfo
* and Descriptors for the ModelMBean instance. The attributes and operations
* exposed via the ModelMBeanInfo for the ModelMBean are accessible
* from MBeans, connectors/adaptors like other MBeans. Through the Descriptors,
* values and methods in the managed application can be defined and mapped to
* attributes and operations of the ModelMBean.
* This mapping can be defined during development in a file or dynamically and
* programmatically at runtime.
* <P>
* Every ModelMBean which is instantiated in the MBeanServer becomes manageable:
* its attributes and operations
* become remotely accessible through the connectors/adaptors connected to that
* MBeanServer.
* A Java object cannot be registered in the MBeanServer unless it is a JMX
* compliant MBean.
* By instantiating a ModelMBean, resources are guaranteed that the MBean is
* valid.
*
* MBeanException and RuntimeOperationsException must be thrown on every public
* method. This allows for wrapping exceptions from distributed
* communications (RMI, EJB, etc.)
*
* <p>The <b>serialVersionUID</b> of this class is
* <code>-1935722590756516193L</code>.
