void check(const ast_matchers::MatchFinder::MatchResult &Result) override
ClangTidyChecks that register ASTMatchers should do the actual work in here.
StringHandle Name
std::unique_ptr< ast_matchers::MatchFinder > Finder

Base class for all clang-tidy checks.
Definition: ClangTidy.h:102
Checks for use of implicit bool casts in expressions.
void registerMatchers(ast_matchers::MatchFinder *Finder) override
Override this to register ASTMatchers with Finder.
ImplicitBoolCastCheck(StringRef Name, ClangTidyContext *Context)
Every ClangTidyCheck reports errors through a DiagnosticsEngine provided by this context.
