Detailed Description

A (possibly-)qualified type.

For efficiency, we don't store CV-qualified types as nodes on their own: instead each reference to a type stores the qualifiers. This greatly reduces the number of nodes we need to allocate for types (for example we only need one for 'int', 'const int', 'volatile int', 'const volatile int', etc).

As an added efficiency bonus, instead of making this a pair, we just store the two bits we care about in the low bits of the pointer. To handle the packing/unpacking, we make QualType be a simple wrapper class that acts like a smart pointer. A third bit indicates whether there are extended qualifiers present, in which case the pointer points to a special structure.

◆ PrimitiveCopyKind

enum clang::QualType::PrimitiveCopyKind

Enumerator
PCK_Trivial	The type does not fall into any of the following categories. Note that this case is zero-valued so that values of this enum can be used as a boolean condition for non-triviality.
PCK_VolatileTrivial	The type would be trivial except that it is volatile-qualified. Types that fall into one of the other non-trivial cases may additionally be volatile-qualified.
PCK_ARCStrong	The type is an Objective-C retainable pointer type that is qualified with the ARC __strong qualifier.
PCK_ARCWeak	The type is an Objective-C retainable pointer type that is qualified with the ARC __weak qualifier.
PCK_PtrAuth	The type is an address-discriminated signed pointer type.
PCK_Struct	The type is a struct containing a field whose type is neither PCK_Trivial nor PCK_VolatileTrivial. Note that a C++ struct type does not necessarily match this; C++ copying semantics are too complex to express here, in part because they depend on the exact constructor or assignment operator that is chosen by overload resolution to do the copy.

◆ PrimitiveDefaultInitializeKind

enum clang::QualType::PrimitiveDefaultInitializeKind

Enumerator
PDIK_Trivial	The type does not fall into any of the following categories. Note that this case is zero-valued so that values of this enum can be used as a boolean condition for non-triviality.
PDIK_ARCStrong	The type is an Objective-C retainable pointer type that is qualified with the ARC __strong qualifier.
PDIK_ARCWeak	The type is an Objective-C retainable pointer type that is qualified with the ARC __weak qualifier.
PDIK_Struct	The type is a struct containing a field whose type is not PCK_Trivial.

Return the specified type with any "sugar" removed from the type.

This takes off typedefs, typeof's etc. If the outer level of the type is already concrete, it returns it unmodified. This is similar to getting the canonical type, but it doesn't remove all typedefs. For example, it returns "T*" as "T*", (not as "int*"), because the pointer is concrete.

Qualifiers are left in place.

◆ getNonReferenceType()

If Type is a reference type (e.g., const int&), returns the type that the reference refers to ("const int").

Otherwise, returns the type itself. This routine is used throughout Sema to implement C++ 5p6:

If an expression initially has the type "reference to T" (8.3.2, 8.5.3), the type is adjusted to "T" prior to any further analysis, the expression designates the object or function denoted by the reference, and the expression is an lvalue.

◆ getUnqualifiedType()

QualType clang::QualType::getUnqualifiedType ( ) const

inline

Retrieve the unqualified variant of the given type, removing as little sugar as possible.

This routine looks through various kinds of sugar to find the least-desugared type that is unqualified. For example, given:

typedef int Integer;
typedef const Integer CInteger;
typedef CInteger DifferenceType;

Executing getUnqualifiedType() on the type DifferenceType will desugar until we hit the type Integer, which has no qualifiers on it.

The resulting type might still be qualified if it's sugar for an array type. To strip qualifiers even from within a sugared array type, use ASTContext::getUnqualifiedArrayType.

Note: In C, the _Atomic qualifier is special (see C23 6.2.5p32 for details), and it is not stripped by this function. Use getAtomicUnqualifiedType() to strip qualifiers including _Atomic.

Return true if the type is safe to bitwise copy using memcpy/memmove.

This is an extension in clang: bitwise cloneable types act as trivially copyable types, meaning their underlying bytes can be safely copied by memcpy or memmove. After the copy, the destination object has the same object representation.

However, there are cases where it is not safe to copy:

When sanitizers, such as AddressSanitizer, add padding with poison, which can cause issues if those poisoned padding bits are accessed.
Types with Objective-C lifetimes, where specific runtime semantics may not be preserved during a bitwise copy.

Check if this is a non-trivial type that would cause a C struct transitively containing this type to be non-trivial to destructively move and return the kind.

Destructive move in this context is a C++-style move in which the source object is placed in a valid but unspecified state after it is moved, as opposed to a truly destructive move in which the source object is placed in an uninitialized state.

◆ substObjCMemberType()

QualType QualType::substObjCMemberType	(	QualType	objectType,
		const DeclContext *	dc,
		ObjCSubstitutionContext	context ) const

Substitute type arguments from an object type for the Objective-C type parameters used in the subject type.

This operation combines the computation of type arguments for substitution (Type::getObjCSubstitutions) with the actual process of substitution (QualType::substObjCTypeArgs) for the convenience of callers that need to perform a single substitution in isolation.

Parameters

objectType	The type of the object whose member type we're substituting into. For example, this might be the receiver of a message or the base of a property access.
dc	The declaration context from which the subject type was retrieved, which indicates (for example) which type parameters should be substituted.
context	The context in which the subject type was written.

Returns: the subject type after replacing all of the Objective-C type parameters with their corresponding arguments.

◆ substObjCTypeArgs()

QualType QualType::substObjCTypeArgs	(	ASTContext &	ctx,
		ArrayRef< QualType >	typeArgs,
		ObjCSubstitutionContext	context ) const

Substitute type arguments for the Objective-C type parameters used in the subject type.

Substitute the given type arguments for Objective-C type parameters within the given type, recursively.

Parameters

ctx	ASTContext in which the type exists.
typeArgs	The type arguments that will be substituted for the Objective-C type parameters in the subject type, which are generally computed via `Type::getObjCSubstitutions`. If empty, the type parameters will be replaced with their bounds or id/Class, as appropriate for the context.
context	The context in which the subject type was written.

Returns: the resulting type.
