Token Name
Base class for all clang-tidy checks.
Every ClangTidyCheck reports errors through a DiagnosticsEngine provided by this context.
Finds symbol which have confusable identifiers, i.e.
void check(const ast_matchers::MatchFinder::MatchResult &Result) override
ClangTidyChecks that register ASTMatchers should do the actual work in here.
void registerMatchers(ast_matchers::MatchFinder *Finder) override
Override this to register AST matchers with Finder.
