Enumeration Type Documentation

◆ QualifierPolicy

enum class clang::tidy::utils::fixit::QualifierPolicy

strong

This enum defines where the qualifier shall be preferably added.

Enumerator
Left
Right

Definition at line 23 of file FixItHintUtils.h.

◆ QualifierTarget

enum class clang::tidy::utils::fixit::QualifierTarget

strong

This enum defines which entity is the target for adding the qualifier.

This makes only a difference for pointer-types. Other types behave identical for either value of ConstTarget.

Enumerator

Pointee

Value

Transforming a pointer attaches to the pointee and not the pointer itself.

For references and normal values this option has no effect. int * p = &i; -> const int * p = &i or int const


p = &i.

Definition at line 31 of file FixItHintUtils.h.

Function Documentation

◆ addQualifierToVarDecl()

std::optional< FixItHint > clang::tidy::utils::fixit::addQualifierToVarDecl	(	const VarDecl &	Var,
		const ASTContext &	Context,
		DeclSpec::TQ	Qualifier,
		QualifierTarget	QualTarget = `QualifierTarget::Pointee`,
		QualifierPolicy	QualPolicy = `QualifierPolicy::Left`
	)

Creates fix to qualify VarDecl with the specified Qualifier.

Requires that Var is isolated in written code like in int foo = 42;.
