Constructor Detail

MCComponentAdapter

public MCComponentAdapter(org.jboss.kernel.spi.dependency.KernelController controller,
                          org.picocontainer.ComponentAdapter delegate,
                          InterceptMC interceptMC,
                          org.jboss.beans.metadata.plugins.AbstractBeanMetaData data)

The only constructor.

Parameters:

controller - Kernel controller to use

delegate - original component adapter

interceptMC - mc-integration configuration in the form of annotation

Method Detail

getComponentKey

public Object getComponentKey()

Getter method for component key.

Specified by:

getComponentKey in interface org.picocontainer.ComponentAdapter

Returns:

String or Class representing a key

getComponentImplementation

public Class getComponentImplementation()

Getter for component implementation class.

Specified by:

getComponentImplementation in interface org.picocontainer.ComponentAdapter

Returns:

component implementation class

getComponentInstance

public Object getComponentInstance(org.picocontainer.PicoContainer container)
                            throws org.picocontainer.PicoInitializationException,
                                   org.picocontainer.PicoIntrospectionException

This is where mc integration happens. Instantiation is first delegated to original component adapter, the resulting instance is then sent through kernel controller to be injected by mc kernel.

Specified by:

getComponentInstance in interface org.picocontainer.ComponentAdapter

Parameters:

container - pico container that holds this component adapter

Returns:

object with injections already performed on it

Throws:

org.picocontainer.PicoInitializationException

org.picocontainer.PicoIntrospectionException

verify

public void verify(org.picocontainer.PicoContainer container)
            throws org.picocontainer.PicoIntrospectionException

Delegation-only method.

Specified by:

verify in interface org.picocontainer.ComponentAdapter

Parameters:

container -

Throws:

org.picocontainer.PicoIntrospectionException

accept

public void accept(org.picocontainer.PicoVisitor visitor)

Delegation-only method.

Specified by:

accept in interface org.picocontainer.ComponentAdapter

Parameters:

visitor -
