java.lang.Object dk.rode.thesis.meta.reflect.CallerClass.CallerIterator<C>
C
- The specific (sub-) type of the caller class to iterate over.protected abstract static class CallerClass.CallerIterator<C extends CallerClass>
A caller iterator is used to iterator over CallerClass
instances, or sub-classes of it.
Implementation notes:
This is an application of the Iterator
pattern specialised for sub-classes of CallerClass
. The
setNext()
method can on a fine day be considered an application
of the Factory Method pattern.
