public abstract class AbstractCglibSubclassCreator

extends java.lang.Object

Abstract base class for generating and instantiating subclasses of beans. This beans are usually defined in a jsf-spring bean container.

This class should be used for generating proxies. The main domain of this creator is building subclasses/proxies for special InstantiationStrategys or InstantiationProcessors.

Constructor Detail

AbstractCglibSubclassCreator

public AbstractCglibSubclassCreator(java.lang.Class superClass,
                                    java.lang.String beanName)

Constructs a cglib creator for subclassing beans of type superClass with name beanName.

Parameters:

superClass - the type of the bean to subclass

beanName - the name of the bean to subclass

Method Detail

instantiate

public final java.lang.Object instantiate(java.lang.reflect.Constructor ctor,
                                          java.lang.Object[] args)

Create a new instance of a dynamically generated subclass.

Parameters:

ctor - constructor to use. If this is null, use the no-arg constructor (no parameterization or setter injection)

args - arguments to use for the constructor. Ignored if the ctor parameter is null.

Returns:

new instance of the dynamically generated class

instantiate

public final java.lang.Object instantiate(java.lang.Class[] superInterfaces,
                                          java.lang.reflect.Constructor ctor,
                                          java.lang.Object[] args)

Create a new instance of a dynamically generated subclass.

Parameters:

superInterfaces - super interfaces to be implemented by the generated subclass

ctor - constructor to use. If this is null, use the no-arg constructor (no parameterization or setter injection)

args - arguments to use for the constructor. Ignored if the ctor parameter is null.

Returns:

new instance of the dynamically generated class

createCallbacks

protected abstract net.sf.cglib.proxy.Callback[] createCallbacks()

Create the needed cglib callbacks.

Returns:

the callbacks to invoke on filtered methods

createCallbackFilter

protected abstract net.sf.cglib.proxy.CallbackFilter createCallbackFilter()

Creates the needed cglib callbackFilter.

Returns:

the callback filter filtering the matching methods to override/implement
