Detailed Description

This check finds macro expansions of DISALLOW_COPY_AND_ASSIGN(Type) and replaces them with a deleted copy constructor and a deleted assignment operator.

Before:

class Foo {
private:
DISALLOW_COPY_AND_ASSIGN(Foo);
};

After:

class Foo {
private:
Foo(const Foo &) = delete;
const Foo &operator=(const Foo &) = delete;
};

◆ getMacroName()

◆ isLanguageVersionSupported()

bool clang::tidy::modernize::ReplaceDisallowCopyAndAssignMacroCheck::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.

◆ registerPPCallbacks()

void clang::tidy::modernize::ReplaceDisallowCopyAndAssignMacroCheck::registerPPCallbacks ( const SourceManager &  SM,
Preprocessor *  PP,
Preprocessor *  ModuleExpanderPP 
)
overridevirtual

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.

◆ storeOptions()

void clang::tidy::modernize::ReplaceDisallowCopyAndAssignMacroCheck::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.
