The Contract Enforcement Aspect Pattern

Free registration required

Executive Summary

The most fundamental motivation for employing contracts in the development of OO applications is to improve the reliability. Contract enforcement is a well-known established technique in Object-Oriented (OO) programming. However, the need to intercept well defined points in the execution of a program to check design constraints makes the enforcement of contracts a crosscutting concern. Thus, contract enforcement code is inter-wined with the business code, hindering maintenance. Moreover, because of the difficulty in separating contract enforcement code and business code, the former is often duplicated across several different places within a system.
