FloatLoopCounter(StringRef Name, ClangTidyContext *Context)
This check diagnoses when the loop induction expression of a for loop has floating-point type...

void registerMatchers(ast_matchers::MatchFinder *Finder) override
Override this to register AST matchers with Finder.
Every ClangTidyCheck reports errors through a DiagnosticsEngine provided by this context.
void check(const ast_matchers::MatchFinder::MatchResult &Result) override
ClangTidyChecks that register ASTMatchers should do the actual work in here.
