Method of providing persistence to object in C++ object oriented programming system

Abstract

The present invention provides a method of providing persistence to objects which are to be created in a C++ application program, which may present to an user an interface for creating persistent objects with a same concept to that to create transient object in a C++ application program and method of implementing the interface. The present method includes overloading an object creation operator (new( )) into a persistent capable class (OM_POBJECT) as a C++ application program interface of an object oriented database system to use an object creation operator without parameter(OM_POBJECT::new( )), an object creation operator having persistence as parameters(OM_POBJECT::new(persistence)), and an object creation operator having persistence and typename parameters(OM_POBJECT::new(persistence, typename); and using a step of operating the persistence object creation operator and a step of operating a constructor function to support the interface.
