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.

QualType clang::QualType::getDesugaredType ( const ASTContext Context) const [inline]

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.

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.

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

bool clang::QualType::isCanonical ( ) const [inline]

Determine whether expressions of the given type are forbidden from being lvalues in C.

The expression types that are forbidden to be lvalues are:

  • 'void', but not qualified void
  • function types

The exact rule here is C99 6.3.2.1: An lvalue is an expression with an object type or an incomplete type other than void.

Determine whether this type is more qualified than the other given type, requiring exact equality for non-CVR qualifiers.

Determine whether this type is more qualified than the Other type.

For example, "const volatile int" is more qualified than "const int", "volatile int", and "int". However, it is not more qualified than "const volatile int".

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:
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.

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:
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.
