Constructor Detail

JMXExposed

public JMXExposed(ComponentAdapter<T> delegate,
          MBeanServer mBeanServer,
          DynamicMBeanProvider[] providers)
           throws NullPointerException

Construct a JMXExposed behaviour

Parameters:

delegate - The delegated ComponentAdapter.

mBeanServer - The MBeanServer used for registering the MBean.

providers - An array with providers for converting the component instance into a DynamicMBean.

Throws:

NullPointerException - Thrown if the MBeanServer or the array with the DynamicMBeanProvider instances is null.

JMXExposed

public JMXExposed(ComponentAdapter<T> delegate,
          MBeanServer mBeanServer)
           throws NullPointerException

Construct a JMXExposed behaviour. This instance uses a DynamicMBeanComponentProvider as default to register any component instance in the MBeanServer, that is already a DynamicMBean.

Parameters:

delegate - The delegated ComponentAdapter.

mBeanServer - The MBeanServer used for registering the MBean.

Throws:

NullPointerException - Thrown if the MBeanServer or the array with the DynamicMBeanProvider instances is null.

Method Detail

getComponentInstance

public T getComponentInstance(PicoContainer container,
                     Type into)
                       throws PicoCompositionException

Retrieve the component instance. The implementation will automatically register it in the MBeanServer, if a provider can return a DynamicMBean for it.

Note, that you will have to wrap this ComponentAdapter with a Cached to avoid the registration of the same component again.

Specified by:

getComponentInstance in interface ComponentAdapter<T>

Overrides:

getComponentInstance in class AbstractBehavior<T>

Throws:

PicoCompositionException - Thrown by the delegate or if the registering of the DynamicMBean in the MBeanServer fails.
