    The textual description of an MBean or part of an MBean. This + * description is intended to be displayed to users to help them + * understand what the MBean does. Ultimately it will be the value of + * the {@code getDescription()} method of an {@link MBeanInfo}, {@link + * MBeanAttributeInfo}, or similar.

    + * + *

    This annotation applies to Standard MBean interfaces and to + * MXBean interfaces, as well as to MBean classes defined using the + * {@link MBean @MBean} or {@link MXBean @MXBean} annotations. For + * example, a Standard MBean might be defined like this:

    + * + * 
    + * {@code @Description}("Application configuration")
+ * public interface ConfigurationMBean {
+ *     {@code @Description}("Cache size in bytes")
+ *     public int getCacheSize();
+ *     public void setCacheSize(int size);
+ *
+ *     {@code @Description}("Last time the configuration was changed, " +
+ *                  "in milliseconds since 1 Jan 1970")
+ *     public long getLastChangedTime();
+ *
+ *     {@code @Description}("Save the configuration to a file")
+ *     public void save(
+ *         {@code @Description}("Optional name of the file, or null for the default name")
+ *         String fileName);
+ * }
+ *
    + * + *

    The {@code MBeanInfo} for this MBean will have a {@link + * MBeanInfo#getDescription() getDescription()} that is {@code + * "Application configuration"}. It will contain an {@code + * MBeanAttributeInfo} for the {@code CacheSize} attribute that is + * defined by the methods {@code getCacheSize} and {@code + * setCacheSize}, and another {@code MBeanAttributeInfo} for {@code + * LastChangedTime}. The {@link MBeanAttributeInfo#getDescription() + * getDescription()} for {@code CacheSize} will be {@code "Cache size + * in bytes"}. Notice that there is no need to add a + * {@code @Description} to both {@code getCacheSize} and {@code + * setCacheSize} - either alone will do. But if you do add a + * {@code @Description} to both, it must be the same.

    + * + *

    The {@code MBeanInfo} will also contain an {@link + * MBeanOperationInfo} where {@link + * MBeanOperationInfo#getDescription() getDescription()} is {@code + * "Save the configuration to a file"}. This {@code + * MBeanOperationInfo} will contain an {@link MBeanParameterInfo} + * where {@link MBeanParameterInfo#getDescription() getDescription()} + * is {@code "Optional name of the file, or null for the default + * name"}.

    + * + *

    The {@code @Description} annotation can also be applied to the + * public constructors of the implementation class. Continuing the + * above example, the {@code Configuration} class implementing {@code + * ConfigurationMBean} might look like this:

    + * + * 
    + * public class Configuration implements ConfigurationMBean {
+ *     {@code @Description}("A Configuration MBean with the default file name")
+ *     public Configuration() {
+ *         this(DEFAULT_FILE_NAME);
+ *     }
+ *
+ *     {@code @Description}("A Configuration MBean with a specified file name")
+ *     public Configuration(
+ *         {@code @Description}("Name of the file the configuration is stored in")
+ *         String fileName) {...}
+ *     ...
+ * }
+ *
    + * + *

    The {@code @Description} annotation also works in MBeans that + * are defined using the {@code @MBean} or {@code @MXBean} annotation + * on classes. Here is an alternative implementation of {@code + * Configuration} that does not use an {@code ConfigurationMBean} + * interface.

    + * + * 
    + * {@code @MBean}
+ * {@code @Description}("Application configuration")
+ * public class Configuration {
+ *     {@code @Description}("A Configuration MBean with the default file name")
+ *     public Configuration() {
+ *         this(DEFAULT_FILE_NAME);
+ *     }
+ *
+ *     {@code @Description}("A Configuration MBean with a specified file name")
+ *     public Configuration(
+ *         {@code @Description}("Name of the file the configuration is stored in")
+ *         String fileName) {...}
+ *
+ *     {@code @ManagedAttribute}
+ *     {@code @Description}("Cache size in bytes")
+ *     public int getCacheSize() {...}
+ *     {@code @ManagedAttribute}
+ *     public void setCacheSize(int size) {...}
+ *
+ *     {@code @ManagedOperation}
+ *     {@code @Description}("Last time the configuration was changed, " +
+ *                  "in milliseconds since 1 Jan 1970")
+ *     public long getLastChangedTime() {...}
+ *
+ *     {@code @ManagedOperation}
+ *     {@code @Description}("Save the configuration to a file")
+ *     public void save(
+ *         {@code @Description}("Optional name of the file, or null for the default name")

    Annotation that adds fields to a {@link Descriptor}. This can be the + * Descriptor for an MBean, or for an attribute, operation, or constructor + * in an MBean, or for a parameter of an operation or constructor.

    + * + *

    Consider this Standard MBean interface, for example:

    + * + * 
    + * public interface CacheControlMBean {
+ *     @DescriptorFields("units=bytes")
+ *     public long getCacheSize();

+ *
    + * + *

    When a Standard MBean is made using this interface, the usual rules + * mean that it will have an attribute called {@code CacheSize} of type + * {@code long}. The {@code DescriptorFields} annotation will ensure + * that the {@link MBeanAttributeInfo} for this attribute will have a + * {@code Descriptor} that has a field called {@code units} with + * corresponding value {@code bytes}.

    + * + *

    Similarly, if the interface looks like this:

    + * + * 
    + * public interface CacheControlMBean {
+ *     @DescriptorFields({"units=bytes", "since=1.5"})
+ *     public long getCacheSize();

    Interface annotations are checked only on the exact interface + * that defines the management interface of a Standard MBean or an + * MXBean, not on its parent interfaces.

An MBean can also implement this interface in order + * to get a reference to the MBean Server and/or its name within that + * MBean Server.

    + * + *

    Resource injection

    + * + *

    As an alternative to implementing {@code MBeanRegistration}, if all that + * is needed is the MBean Server or ObjectName then an MBean can use + * resource injection.

    + * + *

    If a field in the MBean object has type {@link ObjectName} and has + * the {@link javax.annotation.Resource @Resource} annotation, + * then the {@code ObjectName} under which the MBean is registered is + * assigned to that field during registration. Likewise, if a field has type + * {@link MBeanServer} and the @Resource annotation, then it will + * be set to the {@code MBeanServer} in which the MBean is registered.

    + * + *

    For example:

    + * + * 
    + * public Configuration implements ConfigurationMBean {
+ *     @Resource
+ *     private volatile MBeanServer mbeanServer;
+ *     @Resource
+ *     private volatile ObjectName objectName;
+ *     ...
+ *     void unregisterSelf() throws Exception {
+ *         mbeanServer.unregisterMBean(objectName);
+ *     }
+ * }
+ *
    + * + *

    Resource injection can also be used on fields of type + * {@link SendNotification} to simplify notification sending. Such a field + * will get a reference to an object of type {@code SendNotification} when + * the MBean is registered, and it can use this reference to send notifications. + * For example:

    + * + * 
    + * public Configuration implements ConfigurationMBean {
+ *     @Resource
+ *     private volatile SendNotification sender;
+ *     ...
+ *     private void updated() {
+ *         Notification n = new Notification(...);
+ *         sender.sendNotification(n);
+ *     }
+ * }
+ *
    + * + *

    A field to be injected must not be static. It is recommended that + * such fields be declared {@code volatile}.

    + * + *

    It is also possible to use the @Resource annotation on + * methods. Such a method must have a {@code void} return type and a single + * argument of the appropriate type, for example {@code ObjectName}.

    + * + *

    Any number of fields and methods may have the @Resource + * annotation. All fields and methods with type {@code ObjectName} + * (for example) will receive the same {@code ObjectName} value.

    + * + *

    Resource injection is available for all types of MBeans, not just + * Standard MBeans.

    + * + *

    If an MBean implements the {@link DynamicWrapperMBean} interface then + * resource injection happens on the object returned by that interface's + * {@link DynamicWrapperMBean#getWrappedObject() getWrappedObject()} method + * rather than on the MBean object itself. + * + *

    Resource injection happens after the {@link #preRegister preRegister} + * method is called (if any), and before the MBean is actually registered + * in the MBean Server. If a @Resource method throws + * an exception, the effect is the same as if {@code preRegister} had + * thrown the exception. In particular it will prevent the MBean from being + * registered.

    + * + *

    Resource injection can be used on a field or method where the type + * is a parent of the injected type, if the injected type is explicitly + * specified in the @Resource annotation. For example:

    + * + * 
    + *     @Resource(type = MBeanServer.class)
+ *     private volatile MBeanServerConnection mbsc;
+ *
    + * + *

    Formally, suppose R is the type in the @Resource + * annotation and T is the type of the method parameter or field. + * Then one of R and T must be a subtype of the other + * (or they must be the same type). Injection happens if this subtype + * is {@code MBeanServer}, {@code ObjectName}, or {@code SendNotification}. + * Otherwise the @Resource annotation is ignored.

    + * + *

    Resource injection in MBeans is new in version 2.0 of the JMX API.
