<h1>Exiv2::Internal::TiffComponent Class Reference</h1><!-- doxytag: class="Exiv2::Internal::TiffComponent" -->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.

<hr><a name="_details"></a><h2>Detailed Description</h2>
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. <hr><h2>Member Function Documentation</h2>
