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.

Member Enumeration Documentation

◆ DestructionKind

Enumerator
DK_none 
DK_cxx_destructor 
DK_objc_strong_lifetime 
DK_objc_weak_lifetime 
DK_nontrivial_c_struct 

Definition at line 1147 of file Type.h.

◆ 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_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.

Definition at line 1106 of file Type.h.

◆ 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.

◆ getDesugaredType()

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.

◆ getNonLValueExprType()

QualType QualType::getNonLValueExprType ( const ASTContext Context) const

Determine the type of a (typically non-lvalue) expression with the specified result type.

This routine should be used for expressions for which the return type is explicitly specified (e.g., in a cast or call) and isn't necessarily an lvalue. It removes a top-level reference (since there are no expressions of reference type) and deletes top-level cvr-qualifiers from non-class types (in C++) or all types (in C).

◆ getNonReferenceType()

QualType clang::QualType::getNonReferenceType ( ) const
inline

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.

◆ getTypePtrOrNull()

const Type * clang::QualType::getTypePtrOrNull ( ) const
inline

◆ 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.

◆ substObjCMemberType()

QualType QualType::substObjCMemberType ( QualType  objectType,
const DeclContext dc,

) 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
objectTypeThe 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.
dcThe declaration context from which the subject type was retrieved, which indicates (for example) which type parameters should be substituted.
contextThe 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.

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
ctxASTContext in which the type exists.
typeArgsThe 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.
contextThe context in which the subject type was written.
Returns
the resulting type.
