[Trilinos-Users] NOX epetra computeF

I am confused with the computeF method in a Newton non linear solve using NOX. 
If I compute the residual of the type:
J dx = F - R
J = Jacobian
dx = solution increment
R = Imbalance force vector
F = external force

Do I have to increment the solution x at time n+1 such that x_(n+1) = x_n+dx 
in the routine computeF or this is already performed in an other routine?

Best regards
