No, this interface uses a solve function, in which the algebraic and numeric factorisation is done each time the solve() function is called. This has something to do with the common interface for the direct and iterative solvers. But it is easy to implement yourself, take a look into lac/trilinos_sovler.h and lac/trilinos_solver.cc to see how the Amesos package is called.
