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

Class DeclarationEntry

A C/C++ declaration entry. For example the following code contains five declaration entries:

extern int myGlobal;
int myVariable;
typedef char MyChar;
void myFunction();
void myFunction() {
  // ...

See the comment above Declaration for an explanation of the relationship between Declaration and DeclarationEntry.

Direct supertypes

Indirect supertypes

Known direct subtypes



Gets a specifier associated with this declaration entry.


Gets the name associated with the corresponding definition (where available), or the name declared by this entry otherwise.


Gets the declaration for which this is a declaration entry.


Gets the name associated with this declaration entry, if any.


Gets the type associated with this declaration entry.


Gets the type associated with this declaration entry after specifiers have been deeply stripped and typedefs have been resolved.


Holds if this declaration entry has a specifier with the given name.


Holds if this declaration entry is a definition.


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 primary location of this element.

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 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.
