Detailed Description

The OKS class.

An OKS class has name, documentation, attributes (list of OksAttribute objects), relationships (list of OksRelationship objects) and methods (list of OksMethod objects).

A class may participate in inheritance (multiple): in such case the class inherits all attributes, relationships and methods of its base classes.

An OKS class can be abstract (i.e. it does not have any instances). Otherwise the objects of class can be accessed via:

• objects() : get all objects of given class
• create_list_of_all_objects() : get all objects of given and derived classes
• get_object(const std::string&) : get object by unique identity
• execute_query() : get objects satisfying a query See OksObject class to get information how to access properties of object, to create new or to delete existing object.

An OKS class can be made persistent, i.e. stored on OKS schema file.
