public class ClassFinder
- extends AbstractFinder
ClassFinder searches the classpath of the specified classloader for
packages, classes, constructors, methods, or fields with specific annotations.
For security reasons ASM is used to find the annotations. Classes are not
loaded unless they match the requirements of a called findAnnotated* method.
Once loaded, these classes are cached.
The getClassesNotLoaded() method can be used immediately after any find*
method to get a list of classes which matched the find requirements (i.e.
contained the annotation), but were unable to be loaded.
