Detailed Description

Replace copy and swap tricks on shrinkable containers with the shrink_to_fit() method call.

The shrink_to_fit() method is more readable and more effective than the copy and swap trick to reduce the capacity of a shrinkable container. Note that, the shrink_to_fit() method is only available in C++11 and up.

Member Function Documentation

◆ check()

void clang::tidy::modernize::ShrinkToFitCheck::check ( const ast_matchers::MatchFinder::MatchResult &  Result)
overridevirtual

ClangTidyChecks that register ASTMatchers should do the actual work in here.

Reimplemented from clang::tidy::ClangTidyCheck.

Definition at line 56 of file ShrinkToFitCheck.cpp.

◆ registerMatchers()

void clang::tidy::modernize::ShrinkToFitCheck::registerMatchers ( ast_matchers::MatchFinder *  Finder)
overridevirtual

Override this to register AST matchers with Finder.

This should be used by clang-tidy checks that analyze code properties that dependent on AST knowledge.

You can register as many matchers as necessary with Finder. Usually, "this" will be used as callback, but you can also specify other callback classes. Thereby, different matchers can trigger different callbacks.

If you need to merge information between the different matchers, you can store these as members of the derived class. However, note that all matches occur in the order of the AST traversal.

Reimplemented from clang::tidy::ClangTidyCheck.
