From 781ab8407b50d303197ab6fb888ed35ecbcce23a Mon Sep 17 00:00:00 2001 From: Lioncash Date: Mon, 1 Apr 2019 12:29:59 -0400 Subject: general: Use deducation guides for std::lock_guard and std::unique_lock Since C++17, the introduction of deduction guides for locking facilities means that we no longer need to hardcode the mutex type into the locks themselves, making it easier to switch mutex types, should it ever be necessary in the future. --- src/core/perf_stats.cpp | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'src/core/perf_stats.cpp') diff --git a/src/core/perf_stats.cpp b/src/core/perf_stats.cpp index c716a462b..4afd6c8a3 100644 --- a/src/core/perf_stats.cpp +++ b/src/core/perf_stats.cpp @@ -18,13 +18,13 @@ using std::chrono::microseconds; namespace Core { void PerfStats::BeginSystemFrame() { - std::lock_guard lock(object_mutex); + std::lock_guard lock{object_mutex}; frame_begin = Clock::now(); } void PerfStats::EndSystemFrame() { - std::lock_guard lock(object_mutex); + std::lock_guard lock{object_mutex}; auto frame_end = Clock::now(); accumulated_frametime += frame_end - frame_begin; @@ -35,13 +35,13 @@ void PerfStats::EndSystemFrame() { } void PerfStats::EndGameFrame() { - std::lock_guard lock(object_mutex); + std::lock_guard lock{object_mutex}; game_frames += 1; } PerfStatsResults PerfStats::GetAndResetStats(microseconds current_system_time_us) { - std::lock_guard lock(object_mutex); + std::lock_guard lock{object_mutex}; const auto now = Clock::now(); // Walltime elapsed since stats were reset @@ -67,7 +67,7 @@ PerfStatsResults PerfStats::GetAndResetStats(microseconds current_system_time_us } double PerfStats::GetLastFrameTimeScale() { - std::lock_guard lock(object_mutex); + std::lock_guard lock{object_mutex}; constexpr double FRAME_LENGTH = 1.0 / 60; return duration_cast(previous_frame_length).count() / FRAME_LENGTH; -- cgit v1.2.3
