public void clear()

getEjbBeanProxyClass

public Class<?> getEjbBeanProxyClass(OwbBean<?> bean,
                                     Class<?> iface)

Provides the proxy for the given bean and interface, if defined

Parameters:

bean - the contextual representing the EJB

iface - the injected business local interface

Returns:

the proxy Class if one has been defined, else null

defineEjbBeanProxyClass

public Class<?> defineEjbBeanProxyClass(OwbBean<?> bean,
                                        Class<?> iface,
                                        javassist.util.proxy.ProxyFactory factory)

Defines the proxy for the given bean and iface using callers factory. Due to races with the concurrentmap, this might sometimes create additional javassist-defined classes that are not used by the caller and not stored in the map. Synchronizing the entire method, and getEjbBeanProxyClass, on ejbProxyClasses is an alternative.

Parameters:

bean - the contextual representing the EJB

iface - the injected business local interface

factory -

Returns:

createAbstractDecoratorProxyClass

public Class<?> createAbstractDecoratorProxyClass(OwbBean<?> bean)

                                             CreationalContext<?> creastionalContext)

public static WebBeansAnnotation createNewAnnotationProxy(Class<? extends Annotation> annotationType)

isProxyInstance

public static boolean isProxyInstance(Object o)

Parameters:

o - the object to check

Returns:

true if the given object is a proxy
