From 0e29f7974b59e4440cf02e1388fb9d8ab2b5c5fd Mon Sep 17 00:00:00 2001 From: Hein-Pieter van Braam Date: Wed, 25 Jul 2018 03:11:03 +0200 Subject: Reduce unnecessary COW on Vector by make writing explicit This commit makes operator[] on Vector const and adds a write proxy to it. From now on writes to Vectors need to happen through the .write proxy. So for instance: Vector vec; vec.push_back(10); std::cout << vec[0] << std::endl; vec.write[0] = 20; Failing to use the .write proxy will cause a compilation error. In addition COWable datatypes can now embed a CowData pointer to their data. This means that String, CharString, and VMap no longer use or derive from Vector. _ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug builds. This is a lot faster for Vector in the editor and while running tests. The reason why this difference used to exist is because force-inlined methods used to give a bad debugging experience. After extensive testing with modern compilers this is no longer the case. --- modules/visual_script/visual_script.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'modules/visual_script/visual_script.cpp') diff --git a/modules/visual_script/visual_script.cpp b/modules/visual_script/visual_script.cpp index 9dea7a9c9e..de9b3d5a91 100644 --- a/modules/visual_script/visual_script.cpp +++ b/modules/visual_script/visual_script.cpp @@ -771,7 +771,7 @@ void VisualScript::custom_signal_set_argument_type(const StringName &p_func, int ERR_FAIL_COND(instances.size()); ERR_FAIL_COND(!custom_signals.has(p_func)); ERR_FAIL_INDEX(p_argidx, custom_signals[p_func].size()); - custom_signals[p_func][p_argidx].type = p_type; + custom_signals[p_func].write[p_argidx].type = p_type; } Variant::Type VisualScript::custom_signal_get_argument_type(const StringName &p_func, int p_argidx) const { @@ -783,7 +783,7 @@ void VisualScript::custom_signal_set_argument_name(const StringName &p_func, int ERR_FAIL_COND(instances.size()); ERR_FAIL_COND(!custom_signals.has(p_func)); ERR_FAIL_INDEX(p_argidx, custom_signals[p_func].size()); - custom_signals[p_func][p_argidx].name = p_name; + custom_signals[p_func].write[p_argidx].name = p_name; } String VisualScript::custom_signal_get_argument_name(const StringName &p_func, int p_argidx) const { @@ -811,7 +811,7 @@ void VisualScript::custom_signal_swap_argument(const StringName &p_func, int p_a ERR_FAIL_INDEX(p_argidx, custom_signals[p_func].size()); ERR_FAIL_INDEX(p_with_argidx, custom_signals[p_func].size()); - SWAP(custom_signals[p_func][p_argidx], custom_signals[p_func][p_with_argidx]); + SWAP(custom_signals[p_func].write[p_argidx], custom_signals[p_func].write[p_with_argidx]); } void VisualScript::remove_custom_signal(const StringName &p_name) { -- cgit v1.2.3
