Abstract
A method, system, object-oriented system, and computer program product for interfacing two software modules to support various applications. A base class, a zero-level abstract class having a declared virtual function, plural first-level derived classes of the zero-level abstract class having the declared virtual function, and plural second-level classes derived from the base class and the first-level derived classes of the abstract class having the declared virtual function are defined using multiple inheritance so that the virtual function is defined differently for plural instantiated objects of the second-level classes. A first application module communicates with a second application module which processes information to select a software object to be referenced for processing data. The second application module passes a reference defined to reference a first-level derived class and having a value of a reference to the selected software object which is derived from the first-level derived class. The first application module receives the value using a reference defined to reference the zero-level abstract class and then accesses the virtual function defined for the selected sof…
