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. --- editor/plugins/sprite_editor_plugin.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'editor/plugins/sprite_editor_plugin.cpp') diff --git a/editor/plugins/sprite_editor_plugin.cpp b/editor/plugins/sprite_editor_plugin.cpp index 66673cca00..9bf1178b58 100644 --- a/editor/plugins/sprite_editor_plugin.cpp +++ b/editor/plugins/sprite_editor_plugin.cpp @@ -169,7 +169,7 @@ void SpriteEditor::_update_mesh_data() { Size2 img_size = Vector2(image->get_width(), image->get_height()); for (int j = 0; j < lines.size(); j++) { - lines[j] = expand(lines[j], rect, epsilon); + lines.write[j] = expand(lines[j], rect, epsilon); int index_ofs = computed_vertices.size(); -- cgit v1.2.3
