clang::tidy::bugprone::BranchCloneCheck Class Reference

A check for detecting if/else if/else chains where two or more branches are Type I clones of each other (that is, they contain identical code), for detecting switch statements where two or more consecutive branches are Type I clones of each other, and for detecting conditional operators where the true and false expressions are Type I clones of each other.

A check for detecting if/else if/else chains where two or more branches are Type I clones of each other (that is, they contain identical code), for detecting switch statements where two or more consecutive branches are Type I clones of each other, and for detecting conditional operators where the true and false expressions are Type I clones of each other.

Member Function Documentation

◆ check()

void clang::tidy::bugprone::BranchCloneCheck::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 70 of file BranchCloneCheck.cpp.

◆ registerMatchers()

void clang::tidy::bugprone::BranchCloneCheck::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.
