<p>Interface class for components of a TIFF directory hierarchy (Composite pattern). Both TIFF directories as well as entries implement this interface. A component can be uniquely identified by a tag, group tupel. This class is implemented as a NVI (Non-Virtual Interface) and it has an interface for visitors (Visitor pattern) to perform operations on all components.
