llvm::SmallString< 256U > Name
Base class for all clang-tidy checks.
Every ClangTidyCheck reports errors through a DiagnosticsEngine provided by this context.
Detects when a variable is both incremented/decremented and referenced inside a complex condition and...
void registerMatchers(ast_matchers::MatchFinder *Finder) override
Override this to register AST matchers with Finder.
std::optional< TraversalKind > getCheckTraversalKind() const override
IncDecInConditionsCheck(StringRef Name, ClangTidyContext *Context)
void check(const ast_matchers::MatchFinder::MatchResult &Result) override
ClangTidyChecks that register ASTMatchers should do the actual work in here.
