Methods as Parameters: A Pre-processing Approach in Java
Marco Bellia, M. Eugenia Occhiuto · CINECA IRIS Institutial research information system (University of Pisa) · 2007
In this paper we investigate the possibility of adding higher order functionalities to Java, that is passing methods as parameters to other methods. The approach is based on a mechanism which offers a restricted, disciplined, form of function abstraction but suitable to the integration of high order and object oriented pro- gramming. We discuss how the expressive power of the language is increased. A new syntax is introduced for formal and actual parameters, hence the paper shows an implementation of the extentions based on a preprocessing technique tha maps programs of the extended language into programs of ordinary Java.
