publicstatic boolean isMXBeanInterface (Class<Object> interfaceClass)

Test whether an interface is an MXBean interface.

publicstatic 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:

proxy.getSomeAttribute() which will result in a call to mbs.getAttribute(name, "SomeAttribute").
proxy.setSomeAttribute("whatever") which will result in a call to mbs.setAttribute(name, new Attribute("SomeAttribute", "whatever")).
proxy.someOperation("param1", 2) which will be translated into a call to mbs.invoke(name, "someOperation", <etc>).

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

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

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

publicstatic 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.

publicstatic 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:

proxy.getSimpleAttribute() will result in a call to mbs.getAttribute(name, "SimpleAttribute").
proxy.setSimpleAttribute("whatever") will result in a call to mbs.setAttribute(name, new Attribute("SimpleAttribute", "whatever")).

Because String is a simple type, in the sense of SimpleType, it is not changed in the context of an MXBean. The MXBean proxy behaves the same as a Standard MBean proxy (see newMBeanProxy) for the attribute SimpleAttribute.
proxy.getMappedAttribute() will result in a call to mbs.getAttribute("MappedAttribute"). The MXBean mapping rules mean that the actual type of the attribute MappedAttribute will be CompositeData and that is what the mbs.getAttribute call will return. The proxy will then convert the CompositeData back into the expected type MemoryUsage using the MXBean mapping rules.
Similarly, proxy.setMappedAttribute(memoryUsage) will convert the MemoryUsage argument into a CompositeData before calling mbs.setAttribute.
proxy.someOperation("whatever", memoryUsage) will convert the MemoryUsage argument into a CompositeData and call mbs.invoke. The value returned by mbs.invoke will be also be a CompositeData, and the proxy will convert this into the expected type MemoryUsage using the MXBean mapping rules.

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

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

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

publicstatic 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.
