Constructor Detail

JMXVisitor

public JMXVisitor(MBeanServer server)

Construct a JMXVisitor. This instance will register by default any component in the MBeanServer, that is already a DynamicMBean. The ObjectName will use the default domain of the MBeanServer and has a type key with the class name (without package name) as value.

Parameters:

server - The MBeanServerto use for registering the MBeans.

JMXVisitor

public JMXVisitor(MBeanServer server,
                  DynamicMBeanProvider[] providers)

Construct a JMXVisitor.

Parameters:

server - The MBeanServer to use for registering the MBeans.

providers - The providers to deliver the DynamicMBeans.

Method Detail

traverse

public Object traverse(Object node)

Entry point for the visitor traversal.

Specified by:

traverse in interface org.picocontainer.PicoVisitor

Overrides:

traverse in class org.picocontainer.visitors.AbstractPicoVisitor

Returns:

Returns a Set with all ObjectInstance instances retrieved from the MBeanServer for the registered MBeans.

See Also:

AbstractPicoVisitor.traverse(java.lang.Object)

visitContainer

public boolean visitContainer(org.picocontainer.PicoContainer pico)

Provides the PicoContainer, that can resolve the components to register as MBean.

Specified by:

visitContainer in interface org.picocontainer.PicoVisitor

Overrides:

visitContainer in class org.picocontainer.visitors.TraversalCheckingVisitor

See Also:

PicoVisitor.visitContainer(org.picocontainer.PicoContainer)

visitComponentAdapter

public void visitComponentAdapter(org.picocontainer.ComponentAdapter componentAdapter)

Register the component as MBean. The implementation uses the known DynamicMBeanProvider instances to get the MBean from the component.

Specified by:

visitComponentAdapter in interface org.picocontainer.PicoVisitor

Overrides:

visitComponentAdapter in class org.picocontainer.visitors.TraversalCheckingVisitor

See Also:

PicoVisitor.visitComponentAdapter(org.picocontainer.ComponentAdapter)

register

protected ObjectInstance register(DynamicMBean dynamicMBean,
                                  ObjectName objectName)
                           throws JMXRegistrationException

Register a MBean in the MBeanServer.

Parameters:

dynamicMBean - the DynamicMBean to register.

objectName - the ObjectName of the MBean registered the MBeanServer.

Returns:

Returns the ObjectInstance returned from the MBeanServer after registration.

Throws:

JMXRegistrationException - Thrown if MBean cannot be registered.
