Method Detail

newMBeanProxy

public static <T> T newMBeanProxy(MBeanServerConnection connection,
                                  ObjectName objectName,
                                  Class<T> interfaceClass)

Make a proxy for a Standard MBean in a local or remote MBean Server.

If you have an MBean Server mbs containing an MBean with ObjectName name, and if the MBean's management interface is described by the Java interface MyMBean, you can construct a proxy for the MBean like this:

 MyMBean proxy = JMX.newMBeanProxy(mbs, name, MyMBean.class);
 

Suppose, for example, MyMBean looks like this:

 public interface MyMBean {
     public String getSomeAttribute();
     public void setSomeAttribute(String value);
     public void someOperation(String param1, int param2);
 }
 

Then you can execute:

The object returned by this method is a Proxy whose InvocationHandler is an MBeanServerInvocationHandler.

This method is equivalent to newMBeanProxy(connection, objectName, interfaceClass, false).

Type Parameters:
T - allows the compiler to know that if the interfaceClass parameter is MyMBean.class, for example, then the return type is MyMBean.
Parameters:
connection - the MBean server to forward to.
objectName - the name of the MBean within connection to forward to.
interfaceClass - the management interface that the MBean exports, which will also be implemented by the returned proxy.
Returns:
the new proxy instance.

newMBeanProxy

public static <T> T newMBeanProxy(MBeanServerConnection connection,
                                  ObjectName objectName,
                                  Class<T> interfaceClass,
                                  boolean notificationBroadcaster)

Make a proxy for a Standard MBean in a local or remote MBean Server that may also support the methods of NotificationEmitter.

This method behaves the same as newMBeanProxy(MBeanServerConnection, ObjectName, Class), but additionally, if notificationBroadcaster is true, then the MBean is assumed to be a NotificationBroadcaster or NotificationEmitter and the returned proxy will implement NotificationEmitter as well as interfaceClass. A call to NotificationBroadcaster.addNotificationListener(javax.management.NotificationListener, javax.management.NotificationFilter, java.lang.Object) on the proxy will result in a call to MBeanServerConnection.addNotificationListener(ObjectName, NotificationListener, NotificationFilter, Object), and likewise for the other methods of NotificationBroadcaster and NotificationEmitter.

Type Parameters:
T - allows the compiler to know that if the interfaceClass parameter is MyMBean.class, for example, then the return type is MyMBean.
Parameters:
connection - the MBean server to forward to.
objectName - the name of the MBean within connection to forward to.
interfaceClass - the management interface that the MBean exports, which will also be implemented by the returned proxy.
notificationBroadcaster - make the returned proxy implement NotificationEmitter by forwarding its methods via connection.
Returns:
the new proxy instance.

newMXBeanProxy

public static <T> T newMXBeanProxy(MBeanServerConnection connection,
                                   ObjectName objectName,
                                   Class<T> interfaceClass)

Make a proxy for an MXBean in a local or remote MBean Server.

If you have an MBean Server mbs containing an MXBean with ObjectName name, and if the MXBean's management interface is described by the Java interface MyMXBean, you can construct a proxy for the MXBean like this:

 MyMXBean proxy = JMX.newMXBeanProxy(mbs, name, MyMXBean.class);
 

Suppose, for example, MyMXBean looks like this:

 public interface MyMXBean {
     public String getSimpleAttribute();
     public void setSimpleAttribute(String value);
     public MemoryUsage getMappedAttribute();
     public void setMappedAttribute(MemoryUsage memoryUsage);
     public MemoryUsage someOperation(String param1, MemoryUsage param2);
 }
 

Then:

The object returned by this method is a Proxy whose InvocationHandler is an MBeanServerInvocationHandler.

This method is equivalent to newMXBeanProxy(connection, objectName, interfaceClass, false).

Type Parameters:
T - allows the compiler to know that if the interfaceClass parameter is MyMXBean.class, for example, then the return type is MyMXBean.
Parameters:
connection - the MBean server to forward to.
objectName - the name of the MBean within connection to forward to.
interfaceClass - the MXBean interface, which will also be implemented by the returned proxy.
Returns:
the new proxy instance.

newMXBeanProxy

public static <T> T newMXBeanProxy(MBeanServerConnection connection,
                                   ObjectName objectName,
                                   Class<T> interfaceClass,
                                   boolean notificationBroadcaster)

Make a proxy for an MXBean in a local or remote MBean Server that may also support the methods of NotificationEmitter.

This method behaves the same as newMXBeanProxy(MBeanServerConnection, ObjectName, Class), but additionally, if notificationBroadcaster is true, then the MXBean is assumed to be a NotificationBroadcaster or NotificationEmitter and the returned proxy will implement NotificationEmitter as well as interfaceClass. A call to NotificationBroadcaster.addNotificationListener(javax.management.NotificationListener, javax.management.NotificationFilter, java.lang.Object) on the proxy will result in a call to MBeanServerConnection.addNotificationListener(ObjectName, NotificationListener, NotificationFilter, Object), and likewise for the other methods of NotificationBroadcaster and NotificationEmitter.

Type Parameters:
T - allows the compiler to know that if the interfaceClass parameter is MyMXBean.class, for example, then the return type is MyMXBean.
Parameters:
connection - the MBean server to forward to.
objectName - the name of the MBean within connection to forward to.
interfaceClass - the MXBean interface, which will also be implemented by the returned proxy.
notificationBroadcaster - make the returned proxy implement NotificationEmitter by forwarding its methods via connection.
Returns:
the new proxy instance.

isMXBeanInterface

public static boolean isMXBeanInterface(Class<?> interfaceClass)

Test whether an interface is an MXBean interface. An interface is an MXBean interface if it is annotated @MXBean or @MXBean(true) or if it does not have an @MXBean annotation and its name ends with "MXBean".

Parameters:
interfaceClass - The candidate interface.
Returns:
true if interfaceClass is an interface and meets the conditions described.
Throws:
NullPointerException - if interfaceClass is null.
