CodeQL library for C/C++
codeql/cpp-all 0.13.1 (changelog, source)

Class NameQualifier

A C++ name qualifier, for example N:: in the following code:

namespace N {
  int f() {

int g() {
  return N::f();

Import path

import cpp

Direct supertypes

Indirect supertypes



Gets the expression ultimately qualified by the chain of name qualifiers. For example, f() in N1::N2::f().


Gets a location for this name qualifier.


Gets the name qualifier that qualifies this name qualifier, if any. This is used for name qualifier chains, for example the name qualifier N2:: has a name qualifier N1:: in the chain N1::N2::f().


Gets the element qualified by this name qualifier. For example, f() in N::f().


Gets the qualifying element of this name qualifier. For example, N in N::f().


Gets a textual representation of this element.

Inherited predicates


Gets the source of this element: either itself or a macro that expanded to this element.

from Element

Holds if this element may be from source. This predicate holds for all elements, except for those in the dummy file, whose name is the empty string. The dummy file contains declarations that are built directly into the compiler.

from Element

Gets the name of a primary CodeQL class to which this element belongs.

from ElementBase

Gets the closest Element enclosing this one.

from Element

Gets the primary file where this element occurs.

from Element

Gets the parent scope of this Element, if any. A scope is a Type (Class / Enum), a Namespace, a BlockStmt, a Function, or certain kinds of Statement.

from Element

Gets a comma-separated list of the names of the primary CodeQL classes to which this element belongs.

from ElementBase

Holds if this element has a globally qualified name. For example, ::x is globally qualified. It is used to refer to x in the global namespace.

from NameQualifiableElement

Holds if this element has a __super-qualified name. For example: __super::get(). Note: __super is non-standard C++ extension, only supported by some C++ compilers.

from NameQualifiableElement

Holds if this element is affected in any way by a macro. All elements that are totally or partially generated by a macro are included, so this is a super-set of isInMacroExpansion.

from Element

Holds if this Element is a part of a template instantiation (but not the template itself).

from Element

Holds if this Element is part of a template template (not if it is part of an instantiation of template). This means it is represented in the database purely as syntax and without guarantees on the presence or correctness of type-based operations such as implicit conversions.

from Element

Holds if this element comes from a macro expansion. Only elements that are entirely generated by a macro are included - for elements that partially come from a macro, see isAffectedByMacro.
