Abstract

OPLA is an object-oriented (OO) logic programming language built on top of Common Lisp Object System (CLOS) OPLA enhances logic programming with advanced features of OO paradigm, such as multiple-inheritance, multi-methods, and the constraint-based control flow mechanism. In particular, we discuss the features of the OPLA language used to solve non trivial problems of user-interface development, such as the management of graphical constraints on windows, and the application of law-based delegation. The novel features of OPLA are quantitatively discussed, by reporting their impact in the realization of significant applications
