registerLinearSolverFactory()

void Belos::Details::registerLinearSolverFactory

(

)

Register Belos' LinearSolverFactory with the central repository, for all enabled combinations of template parameters.

For all combinations of template parameters that Belos enables, register Belos::Details::LinearSolverFactory with the central repository. This will let any clients of Trilinos::Details::getLinearSolver create Belos solvers with those template parameters.

You may call this function multiple times; it will only have an effect the first time (it is idempotent).

Users do not normally have to call this function, but see Bug

1. Belos tries its best to register its LinearSolverFactory automatically with the central repository, for all enabled template parameter combinations. You may have to call this function if your C++ compiler does not support the necessary features for automatic registration to work, or if Trilinos was configured with automatic registration turned off (Trilinos_ENABLE_LINEAR_SOLVER_FACTORY_REGISTRATION was set to OFF). It never hurts to invoke this function manually, though.

If you need to register Belos's LinearSolverFactory for a set of template parameters that is not enabled, see Belos_Details_LinearSolverFactory.hpp (in this directory).

Warning

FIXME (mfh 23 Aug 2015) This currently only works if the compiler understands GCC's attribute((weak)) syntax. See the comments in Belos_Details_registerLinearSolverFactory.cpp in this directory. As a work-around, you may invoke Belos::Details::Tpetra::registerLinearSolverFactory() for the Tpetra specialization, or Belos::Details::Epetra::registerLinearSolverFactory() for the Epetra specialization. Either of these requires an extern declaration in your code.
