Detailed Description

This check finds cases where the incorrect Duration factory function is being used by looking for scaling constants inside the factory argument and suggesting a more appropriate factory.

It also looks for the special case of zero and suggests ZeroDuration().

Member Function Documentation

◆ check()

void clang::tidy::abseil::DurationFactoryScaleCheck::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 135 of file DurationFactoryScaleCheck.cpp.

◆ registerMatchers()

void clang::tidy::abseil::DurationFactoryScaleCheck::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.

This will only be executed if the function isLanguageVersionSupported returns true.

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.
