the special cat_device root class
Definition: cat_device.hpp:47
virtual bool operator==(const cat_entree &ref) const override
returns true if the two object are the same
virtual void inherited_dump(const pile_descriptor &pdesc, bool small) const override
true if object has been created by sequential reading of an archive
the root class from all other inherite for any entry in the catalogue
Definition: cat_entree.hpp:60
saved_status get_saved_status() const
obtain the saved status of the object
Definition: cat_entree.hpp:164
