The main documentation of the Initialized_Solver Procedure contains additional explanation of this code listing.
function Initialized_Solver (Solver) result(Initialized)
! Use associations.
use Caesar_Flags_Module, only: initialized_flag
! Input variable.
type(Solver_type), intent(in) :: Solver ! Solver to be checked.
! Output variable.
type(logical) :: Initialized ! Initialized condition boolean.
!~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
! Verify requirements - none.
! Set initialized boolean.
Initialized = Solver%Initialized == initialized_flag
! Verify guarantees - none.
return
end function Initialized_Solver
