Detailed Description

Implements C++ Core Guidelines Type.6.

Checks that every user-provided constructor value-initializes all class members and base classes that would have undefined behavior otherwise. Also check that any record types without user-provided default constructors are value-initialized where used.

Members initialized through function calls in the body of the constructor will result in false positives.

For the user-facing documentation see: http://clang.llvm.org/extra/clang-tidy/checks/cppcoreguidelines-pro-type-member-init.html TODO: See if 'fixes' for false positives are optimized away by the compiler. TODO: For classes with multiple constructors, make sure that we don't offer multiple in-class initializer fixits for the same member.

Member Function Documentation

◆ check()

void clang::tidy::cppcoreguidelines::ProTypeMemberInitCheck::check ( const ast_matchers::MatchFinder::MatchResult &  Result)
overridevirtual

ClangTidyChecks that register ASTMatchers should do the actual work in here.

Reimplemented from clang::tidy::ClangTidyCheck.

Definition at line 312 of file ProTypeMemberInitCheck.cpp.

◆ isLanguageVersionSupported()

bool clang::tidy::cppcoreguidelines::ProTypeMemberInitCheck::isLanguageVersionSupported ( const LangOptions &  LangOpts) const
inlineoverridevirtual

Override this to disable registering matchers and PP callbacks if an invalid language version is being used.

For example if a check is examining overloaded functions then this should be overridden to return false when the CPlusPlus flag is not set in LangOpts.

Reimplemented from clang::tidy::ClangTidyCheck.

Definition at line 37 of file ProTypeMemberInitCheck.h.

◆ registerMatchers()

void clang::tidy::cppcoreguidelines::ProTypeMemberInitCheck::registerMatchers ( ast_matchers::MatchFinder *  Finder)
overridevirtual

Override this to register AST matchers with Finder.

This should be used by clang-tidy checks that analyze code properties that dependent on AST knowledge.

You can register as many matchers as necessary with Finder. Usually, "this" will be used as callback, but you can also specify other callback classes. Thereby, different matchers can trigger different callbacks.

This will only be executed if the function isLanguageVersionSupported returns true.

If you need to merge information between the different matchers, you can store these as members of the derived class. However, note that all matches occur in the order of the AST traversal.

Reimplemented from clang::tidy::ClangTidyCheck.

Definition at line 273 of file ProTypeMemberInitCheck.cpp.

◆ storeOptions()

void clang::tidy::cppcoreguidelines::ProTypeMemberInitCheck::storeOptions ( ClangTidyOptions::OptionMap Options)
overridevirtual

Should store all options supported by this check with their current values or default values for options that haven't been overridden.

The check should use Options.store() to store each option it supports whether it has the default value or it has been overridden.

Reimplemented from clang::tidy::ClangTidyCheck.
