llvm::StringRef Name
MultipleInheritanceCheck(StringRef Name, ClangTidyContext *Context)
Base class for all clang-tidy checks.
Definition: ClangTidy.h:127
void check(const ast_matchers::MatchFinder::MatchResult &Result) override
ClangTidyChecks that register ASTMatchers should do the actual work in here.
===– Representation.cpp - ClangDoc Representation --------—*- C++ -*-===//
Every ClangTidyCheck reports errors through a DiagnosticsEngine provided by this context.
void registerMatchers(ast_matchers::MatchFinder *Finder) override
Override this to register AST matchers with Finder.
Mulitple implementation inheritance is discouraged.
