getDynamicTransformationObserver

public DynamicTransformationObserver getDynamicTransformationObserver(javassist.CtClass clazz)

Returns a dynamic transformation observer for clazz.

Specified by:

getDynamicTransformationObserver in interface DynamicAOPStrategy

Parameters:

clazz - the clazz whose transformation must be observed.

getInterceptorChainObserver

public org.jboss.aop.InterceptorChainObserver getInterceptorChainObserver(Class<?> clazz)

Returns an interceptor chain observer for clazz.

Specified by:

getInterceptorChainObserver in interface DynamicAOPStrategy

Parameters:

clazz - the clazz whose interceptor chains will be observed by the observer returned.
