<h3>Log Message</h3>
<pre>Add WTF::ScopeExit
https://bugs.webkit.org/show_bug.cgi?id=160908
Reviewed by Geoffrey Garen.
Source/WTF:
WTF::ScopeExit and WTF::makeScopeExit let you define an object that will invoke a function when the
object goes out of scope. This is going to be used to avoid spagetti-code and gotos in a future patch.
The class is modeled after the LWG paper "P0052 - Generic Scope Guard and RAII Wrapper for the Standard Library".
* WTF.xcodeproj/project.pbxproj:
* wtf/Scope.h: Added.
(WTF::makeScopeExit):
Tools:
* TestWebKitAPI/CMakeLists.txt:
* TestWebKitAPI/TestWebKitAPI.xcodeproj/project.pbxproj:
* TestWebKitAPI/Tests/WTF/Scope.cpp: Added.
