If a class \f(CW\*(C`Ci\*(C'\fR access a method or attribute of a class \f(CW\*(C`Cj\*(C'\fR, consider \f(CW\*(C`Ci\*(C'\fR a client of the supplier class \&\f(CW\*(C`Cj\*(C'\fR, denoting \f(CW\*(C`Ci => Cj\*(C'\fR. Consider the follow function: .PP .Vb 2 \& client(Ci, Cj) = 1, if (Ci => Cj) and (Ci != Cj) \& client(Ci, Cj) = 0, otherwise. .Ve .PP So \f(CW\*(C`ACC(Cj) = (sum(client(Ci, Cj)), i = 1 to N)\*(C'\fR, where \f(CW\*(C`N\*(C'\fR is the total number of system classes. If the value of this metric is large, a change in the class has substantially more side effects, making maintenance more difficult. .SH "REFERENCES" .IX Header "REFERENCES" .IP "\(bu" 4 Monitoramento de metricas de codigo-fonte em projetos de software livre
