alignOfExpr()

internal::Matcher<Stmt> clang::ast_matchers::alignOfExpr ( const internal::Matcher< UnaryExprOrTypeTraitExpr > &  InnerMatcher )

inline

Same as unaryExprOrTypeTraitExpr, but only matching alignof.

Definition at line 2506 of file ASTMatchers.h.

anything()

internal::TrueMatcher clang::ast_matchers::anything ( )

inline

Matches any node.

Useful when another matcher requires a child matcher, but there's no additional constraint. This will often be used with an explicit conversion to an internal::Matcher<> type such as TypeMatcher.

Example: DeclarationMatcher(anything()) matches all declarations, e.g.,

"int* p" and "void f()" in
  int* p;
  void f();

Usable as: Any Matcher

AST_MATCHER() [7/75]

clang::ast_matchers::AST_MATCHER	(	Expr	,
		isInstantiationDependent
	)

Matches expressions that are instantiation-dependent even if it is neither type- nor value-dependent.

In the following example, the expression sizeof(sizeof(T() + T())) is instantiation-dependent (since it involves a template parameter T), but is neither type- nor value-dependent, since the type of the inner sizeof is known (std::size_t) and therefore the size of the outer sizeof is known.

template<typename T>
void f(T x, T y) { sizeof(sizeof(T() + T()); }

expr(isInstantiationDependent()) matches sizeof(sizeof(T() + T())

For example, the expressions "x" and "x + y" are type-dependent in the following code, but "y" is not type-dependent:

template<typename T>
void add(T x, int y) {
  x + y;
}

expr(isTypeDependent()) matches x + y

The check can produce multiple matches in case of multiple inheritance, e.g.

class A1 { virtual void f(); };
class A2 { virtual void f(); };
class C : public A1, public A2 { void f(); };

cxxMethodDecl(ofClass(hasName("C")), forEachOverridden(cxxMethodDecl().bind("b"))).bind("d") matches twice, once with "b" binding "A1::f" and "d" binding "C::f", and once with "b" binding "A2::f" and "d" binding "C::f".

	)

Matches expressions that match InnerMatcher that are possibly wrapped in an elidable constructor and other corresponding bookkeeping nodes.

In C++17, elidable copy constructors are no longer being generated in the AST as it is not permitted by the standard. They are, however, part of the AST in C++14 and earlier. So, a matcher must abstract over these differences to work in all language modes. This matcher skips elidable constructor-call AST nodes, ExprWithCleanups nodes wrapping elidable constructor-calls and various implicit nodes inside the constructor calls, all of which will not appear in the C++17 AST.

Given

struct H {};
H G();
void f() {
  H D = G();
}

varDecl(hasInitializer(ignoringElidableConstructorCall(callExpr()))) matches H D = G() in C++11 through C++17 (and beyond).

Overloaded to match the declaration of the expression's or value declaration's type.

In case of a value declaration (for example a variable declaration), this resolves one layer of indirection. For example, in the value declaration "X x;", cxxRecordDecl(hasName("X")) matches the declaration of X, while varDecl(hasType(cxxRecordDecl(hasName("X")))) matches the declaration of x.

Example matches x (matcher = expr(hasType(cxxRecordDecl(hasName("X"))))) and z (matcher = varDecl(hasType(cxxRecordDecl(hasName("X"))))) and friend class X (matcher = friendDecl(hasType("X"))

class X {};
void y(X &x) { x; X z; }
class Y { friend class X; };

equals()

template<typename ValueT >

internal::PolymorphicMatcherWithParam1<internal::ValueEqualsMatcher, ValueT> clang::ast_matchers::equals

(

Note that you cannot directly match a negative numeric literal because the minus sign is not part of the literal: It is a unary operator whose operand is the positive numeric literal. Instead, you must use a unaryOperator() matcher to match the minus sign:

unaryOperator(hasOperatorName("-"), hasUnaryOperand(integerLiteral(equals(13))))

For example, in:

class A { class B {}; class C {}; };

The matcher:

cxxRecordDecl(hasName("::A"),
              findAll(cxxRecordDecl(isDefinition()).bind("m")))

will generate results for A, B and C.

hasDeclaration()

internal::PolymorphicMatcherWithParam1< internal::HasDeclarationMatcher, internal::Matcher<Decl>, void(internal::HasDeclarationSupportedTypes)> clang::ast_matchers::hasDeclaration ( const internal::Matcher< Decl > &  InnerMatcher )

inline

Matches a node if the declaration associated with that node matches the given matcher.

The associated declaration is:

• for type nodes, the declaration of the underlying type
• for CallExpr, the declaration of the callee
• for MemberExpr, the declaration of the referenced member
• for CXXConstructExpr, the declaration of the constructor
• for CXXNewExpr, the declaration of the operator new
• for ObjCIvarExpr, the declaration of the ivar

For type nodes, hasDeclaration will generally match the declaration of the sugared type. Given

class X {};
typedef X Y;
Y y;

in varDecl(hasType(hasDeclaration(decl()))) the decl will match the typedefDecl. A common use case is to match the underlying, desugared type. This can be achieved by using the hasUnqualifiedDesugaredType matcher:

varDecl(hasType(hasUnqualifiedDesugaredType(
    recordType(hasDeclaration(decl())))))

In this matcher, the decl will match the CXXRecordDecl of class X.

Usable as: Matcher<AddrLabelExpr>, Matcher<CallExpr>, Matcher<CXXConstructExpr>, Matcher<CXXNewExpr>, Matcher<DeclRefExpr>, Matcher<EnumType>, Matcher<InjectedClassNameType>, Matcher<LabelStmt>, Matcher<MemberExpr>, Matcher<QualType>, Matcher<RecordType>, Matcher<TagType>, Matcher<TemplateSpecializationType>, Matcher<TemplateTypeParmType>, Matcher<TypedefType>, Matcher<UnresolvedUsingType>

	)

Returns the results of matching Matcher on Node.

Collects the BoundNodes of all callback invocations when matching Matcher on Node and returns the collected results.

Multiple results occur when using matchers like forEachDescendant, which generate a result for each sub-match.

If you want to find all matches on the sub-tree rooted at Node (rather than only the matches on Node itself), surround the Matcher with a findAll().

Example matches X, Y, Y::X, Z::Y, Z::Y::X (matcher = cxxRecordDecl(forEach(cxxRecordDecl(hasName("X")))

class X {};
class Y { class X {}; };  // Matches Y, because Y::X is a class of name X

DescendantT must be an AST base type.

As opposed to 'hasDescendant', 'forEachDescendant' will cause a match for each result that matches instead of only on the first one.

Note: Recursively combined ForEachDescendant can cause many matches: cxxRecordDecl(forEachDescendant(cxxRecordDecl( forEachDescendant(cxxRecordDecl()) ))) will match 10 times (plus injected class name matches) on:

class A { class B { class C { class D { class E {}; }; }; }; };
