Analyzes the given classes to determine witch of them are DEM Entity. It adds them to the corresponding DEM list. All read operations are executed by Javassist so classes are not loaded by the JVM.

Parameters:

classes - the classes to analyze

demRegistrator - the DEM registrator

Throws:

pt.digitalis.utils.inspection.exception.ResourceNotFoundException - if any class could not be found or an annotation can't be read

IllegalAccessException

InstantiationException

ClassNotFoundException
