Class VariableDeclarationEntry

A particular declaration or definition of a C/C++ variable. For example, in the following code there are six variable declaration entries - two each for a and d, and one each for b and c:

extern int a;
int a;

void myFunction(int b) {
  int c;
}

namespace N {
  extern int d;
  int d = 1;
}

ParameterDeclarationEntry

Predicates

getAPrimaryQlClass	Gets the name of a primary CodeQL class to which this element belongs.
getASpecifier	Gets a specifier associated with this declaration entry.
getDeclaration	Gets the declaration for which this is a declaration entry.
getLocation	Gets the primary location of this element.
getName	Gets the name, if any, used for the variable at this declaration or definition.
getType	Gets the type of the variable which is being declared or defined.
getVariable	Gets the variable which is being declared or defined.
isDefinition	Holds if this is a definition of a variable.

Inherited predicates

findRootCause	Gets the source of this element: either itself or a macro that expanded to this element.	from Element
fromLibrary	Holds if this element may be from a library.	from Element
fromSource	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
getCanonicalName	Gets the name associated with the corresponding definition (where available), or the name declared by this entry otherwise.	from DeclarationEntry
getCanonicalQLClass	DEPRECATED: use `getAPrimaryQlClass` instead.	from ElementBase
getEnclosingElement	Gets the closest `Element` enclosing this one.	from Element
getFile	Gets the primary file where this element occurs.	from Element
getParentScope	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
getUnspecifiedType	Gets the type associated with this declaration entry after specifiers have been deeply stripped and typedefs have been resolved.	from DeclarationEntry
hasSpecifier	Holds if this declaration entry has a specifier with the given name.	from DeclarationEntry
isAffectedByMacro	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
isFromTemplateInstantiation	Holds if this `Element` is a part of a template instantiation (but not the template itself).	from Element
isFromUninstantiatedTemplate	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
isInMacroExpansion	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`.	from Element
toString	Gets a textual representation of this element.	from DeclarationEntry
