From: Wolfgang Bangerth Date: Thu, 27 Jan 2022 19:22:45 +0000 (-0700) Subject: Avoid 'using namespace' declarations. X-Git-Tag: v9.4.0-rc1~554^2 X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F13300%2Fhead;p=dealii.git Avoid 'using namespace' declarations. These declarations are dangerous and lead to difficult to find errors when used in header files, but also in .cc files when used in scopes that one can re-enter and when we use unity builds. Avoid where possible. --- diff --git a/source/algorithms/timestep_control.cc b/source/algorithms/timestep_control.cc index a0e4670584..00262893d2 100644 --- a/source/algorithms/timestep_control.cc +++ b/source/algorithms/timestep_control.cc @@ -20,101 +20,104 @@ DEAL_II_NAMESPACE_OPEN -using namespace Algorithms; - -TimestepControl::TimestepControl(double start, - double final, - double tolerance, - double start_step, - double print_step, - double max_step) - : start_val(start) - , final_val(final) - , tolerance_val(tolerance) - , start_step_val(start_step) - , max_step_val(max_step) - , min_step_val(0) - , current_step_val(start_step) - , step_val(start_step) - , print_step(print_step) - , next_print_val(print_step > 0. ? start_val + print_step : start_val - 1.) +namespace Algorithms { - now_val = start_val; + TimestepControl::TimestepControl(double start, + double final, + double tolerance, + double start_step, + double print_step, + double max_step) + : start_val(start) + , final_val(final) + , tolerance_val(tolerance) + , start_step_val(start_step) + , max_step_val(max_step) + , min_step_val(0) + , current_step_val(start_step) + , step_val(start_step) + , print_step(print_step) + , next_print_val(print_step > 0. ? start_val + print_step : start_val - 1.) + { + now_val = start_val; + + // avoid compiler warning + (void)min_step_val; + } + + + + void + TimestepControl::declare_parameters(ParameterHandler ¶m) + { + param.declare_entry("Start", "0.", Patterns::Double()); + param.declare_entry("Final", "1.", Patterns::Double()); + param.declare_entry("First step", "1.e-2", Patterns::Double(0.)); + param.declare_entry("Max step", "1.", Patterns::Double(0.)); + param.declare_entry("Tolerance", "1.e-2", Patterns::Double(0.)); + param.declare_entry("Print step", "-1.", Patterns::Double()); + } + + + + void + TimestepControl::parse_parameters(ParameterHandler ¶m) + { + start(param.get_double("Start")); + start_step(param.get_double("First step")); + max_step(param.get_double("Max step")); + final(param.get_double("Final")); + tolerance(param.get_double("Tolerance")); + print_step = param.get_double("Print step"); + } + + + + bool + TimestepControl::advance() + { + bool changed = false; + + // Try incrementing time by s + double now_trial = now_val + step_val; + current_step_val = step_val; + + // If we just missed the final time, increase the step size a bit.
