Constructor Summary

ClassEnhancerImpl(IRegistrationManager registrationManager, IParameterManager parameterManager, IIdentityManager identityManager, IAuthorizationManager authorizationManager)
Constructor.

Method Summary

pt.digitalis.utils.bytecode.holders.ClassHolder	enhance(pt.digitalis.utils.bytecode.holders.ClassHolder clazz) Reads and iterates over the class annotations, processing them according to their target scope.
void	processAnnotation(ClassEnhancementContext classEnhancementContext, pt.digitalis.utils.bytecode.holders.AnnotationHolder annotation, DEMAnnotationLogic annotationLogic) Processes a given type-targeted annotation, enhancing the class with bytecode generated accordingly to the annotation.
void	processAnnotation(ClassEnhancementContext classEnhancementContext, pt.digitalis.utils.bytecode.holders.AttributeHolder attribute, pt.digitalis.utils.bytecode.holders.AnnotationHolder annotation, DEMAnnotationLogic annotationLogic) Processes a given field-targeted annotation, enhancing the class with bytecode generated accordingly to the annotation.
void	processAnnotation(ClassEnhancementContext classEnhancementContext, pt.digitalis.utils.bytecode.holders.MethodHolder method, pt.digitalis.utils.bytecode.holders.AnnotationHolder annotation, DEMAnnotationLogic annotationLogic) Processes a given method-targeted annotation, enhancing the class with bytecode generated accordingly to the annotation.
