Method Summary

Modifier and Type	Method	Description
private void	collectClasses(TypeElement typeElement)	Checks if the type is included by given set of packages and is visible to the initializer and adds it to collected classes Map if it satisfies all conditions.
(package private) void	discoverClasses(RoundEnvironment roundEnv)	Gathers the message/enum classes to process and generate marshallers for.
private static AnnotationValue	getAnnotationValue(AnnotationMirror annotation, String name)	Gets the value of the name element of the annotation.
private Set<String>	getBasePackages()
(package private) Collection<? extends TypeMirror>	getClasses()
(package private) String	getInitializerClassName()
(package private) String	getInitializerFQClassName()
private Set<TypeElement>	getOriginatingClasses()	Extracts the old root elements from the previously generated initializer source code.
(package private) Set<XClass>	getXClasses()
(package private) boolean	isClassAcceptable(XClass c)	Tests if a given class (which may have not been specifically included) is acceptable for inclusion.
private boolean	isPackageIncluded(PackageElement packageElement)	Checks if a package is included in the given set of packages, considering also their subpackages recursively.
private boolean	isPublicElement(TypeElement typeElement)	Checks if the given type and all its outer types up to top level type have the PUBLIC modifier which ensures their visibility to a different package.
