Detailed Description

QualType - 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]

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.

QualType QualType::getNonLValueExprType ( 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).

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

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.

Like getUnqualifiedType(), but also returns the set of qualifiers that were built up.

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

Retrieves a pointer to the underlying (unqualified) type. This should really return a const Type, but it's not worth changing all the users right now.

This function requires that the type not be NULL. If the type might be NULL, use the (slightly less efficient) getTypePtrOrNull().

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 an array type. To strip qualifiers even from within an array type, use ASTContext::getUnqualifiedArrayType.
