◆ createDiag()

DiagnosticBuilder clang::tidy::utils::UseRangesCheck::createDiag ( const CallExpr &  Call)
virtual

Create a diagnostic for the CallExpr Override this to support custom diagnostic messages.

Reimplemented in clang::tidy::boost::UseRangesCheck.

◆ getFreeBeginEndMethods()

ArrayRef< std::pair< StringRef, StringRef > > clang::tidy::utils::UseRangesCheck::getFreeBeginEndMethods ( ) const
virtual

Gets the fully qualified names of begin and end functions.

The functions must take the container as their one and only argument ::std::begin and ::std::end are a common example

Reimplemented in clang::tidy::boost::UseRangesCheck, and clang::tidy::modernize::UseRangesCheck.

◆ getReplacerMap()

virtual ReplacerMap clang::tidy::utils::UseRangesCheck::getReplacerMap ( ) const
pure virtual

Gets a map of function to replace and methods to create the replacements.

Implemented in clang::tidy::boost::UseRangesCheck, and clang::tidy::modernize::UseRangesCheck.

Referenced by registerMatchers().

◆ getReverseDescriptor()

std::optional< UseRangesCheck::ReverseIteratorDescriptor > clang::tidy::utils::UseRangesCheck::getReverseDescriptor ( ) const
virtual

◆ isLanguageVersionSupported()

bool clang::tidy::utils::UseRangesCheck::isLanguageVersionSupported ( const LangOptions &  LangOpts) const
overridevirtual

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 268 of file utils/UseRangesCheck.cpp.

◆ registerMatchers()

void clang::tidy::utils::UseRangesCheck::registerMatchers ( ast_matchers::MatchFinder *  Finder)
finalvirtual

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.

◆ registerPPCallbacks()

void clang::tidy::utils::UseRangesCheck::registerPPCallbacks ( const SourceManager &  SM,
Preprocessor *  PP,
Preprocessor *  ModuleExpanderPP 
)
finalvirtual

Override this to register PPCallbacks in the preprocessor.

This should be used for clang-tidy checks that analyze preprocessor- dependent properties, e.g. include directives and macro definitions.

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

There are two Preprocessors to choose from that differ in how they handle modular #includes:

  • PP is the real Preprocessor. It doesn't walk into modular #includes and thus doesn't generate PPCallbacks for their contents.
  • ModuleExpanderPP preprocesses the whole translation unit in the non-modular mode, which allows it to generate PPCallbacks not only for the main file and textual headers, but also for all transitively included modular headers when the analysis runs with modules enabled. When modules are not enabled ModuleExpanderPP just points to the real preprocessor.

Reimplemented from clang::tidy::ClangTidyCheck.

◆ storeOptions()

void clang::tidy::utils::UseRangesCheck::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.
