Method Detail

provide

public JMXRegistrationInfo provide(PicoContainer picoContainer,
                                   ComponentAdapter componentAdapter)

Create a StandardMBean from the component provided by the ComponentAdapter. One of the registered MBeanInfoProvider instances must provide a MBeanInfo for the component and the registered ObjectNameFactory has to provide a proper ObjectName.

Note: An instance of the component is only created, if a management interface is available.

Specified by:

provide in interface DynamicMBeanProvider

Parameters:

picoContainer - The PicoContainer to resolve dependencies.

componentAdapter - The ComponentAdapter referring the component.

Returns:

Returns the registration information.

DynamicMBeanProvider.provide(org.picocontainer.PicoContainer, org.picocontainer.ComponentAdapter)

getMBeanFactory

protected abstract DynamicMBeanFactory getMBeanFactory()

Returns:

Returns the DynamicMBeanFactory to use.

getObjectNameFactory

protected abstract ObjectNameFactory getObjectNameFactory()

Deliver the ObjectNameFactory used to provide the ObjectName instances registering the MBeans.

Returns:

Return the ObjectNameFactory instance.

getMBeanInfoProviders

protected abstract MBeanInfoProvider[] getMBeanInfoProviders()

Deliver the MBeanInfoProvider instances to use. The instances are used in the delivered sequence to retrieve a MBeanInfo for a MBean to create. It is valid for an implementation to return an empty array.

Returns:

Return an array of MBeanInfoProvider instances.

getManagementInterface

protected abstract Class getManagementInterface(Class implementation,
                                                MBeanInfo mBeanInfo)
                                         throws ClassNotFoundException

Determin the management interface from the component implementation type and an optional MBeanInfo instance.

Parameters:

implementation - The type of the component's implementation.

mBeanInfo - The MBeanInfo to expose the component. May be null.

Returns:

Returns the management interface.

Throws:

ClassNotFoundException - Thrown if no interface can be determined.
