alignOfExpr()

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

inline

Same as unaryExprOrTypeTraitExpr, but only matching alignof.

Definition at line 3049 of file ASTMatchers.h.

References allOf, anyOf, stmt, and unaryExprOrTypeTraitExpr.

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

	)

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();
}

Matches the Nth binding of a DecompositionDecl.

For example, in:

void foo()
{
    int arr[3];
    auto &[f, s, t] = arr;
 
    f = 42;
}

The matcher:

decompositionDecl(hasBinding(0,
bindingDecl(hasName("f").bind("fBinding"))))

matches the decomposition decl with 'f' bound to "fBinding".

AST_POLYMORPHIC_MATCHER_P_OVERLOAD() [6/12]

clang::ast_matchers::AST_POLYMORPHIC_MATCHER_P_OVERLOAD	(	hasType	,
		AST_POLYMORPHIC_SUPPORTED_TYPES(Expr, FriendDecl, TypedefNameDecl, ValueDecl, CXXBaseSpecifier)	,
		internal::Matcher< QualType >	,
		InnerMatcher	,
		0
	)

Matches if the expression's or declaration's type matches a type matcher.

Example matches x (matcher = expr(hasType(cxxRecordDecl(hasName("X"))))) and z (matcher = varDecl(hasType(cxxRecordDecl(hasName("X"))))) and U (matcher = typedefDecl(hasType(asString("int"))) and friend class X (matcher = friendDecl(hasType("X")) and public virtual X (matcher = cxxBaseSpecifier(hasType( asString("class X")))

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

		AST_POLYMORPHIC_SUPPORTED_TYPES(Expr, FriendDecl, ValueDecl, CXXBaseSpecifier)	,
		internal::Matcher< Decl >	,
		InnerMatcher	,
		1
	)

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")) and public virtual X (matcher = cxxBaseSpecifier(hasType( cxxRecordDecl(hasName("X"))))

class X {};
void y(X &x) { x; X z; }
class Y { friend class X; };
class Z : public virtual X {};

Example matches class Derived (matcher = cxxRecordDecl(hasAnyBase(hasType(cxxRecordDecl(hasName("Base"))))))

class Base {};
class Derived : Base {};

Matches C++ or Objective-C classes that are directly derived from a class matching Base.

Note that a class is not considered to be derived from itself.

Example matches Y, C (Base == hasName("X"))

class X;
class Y : public X {};  // directly derived
class Z : public Y {};  // indirectly derived
typedef X A;
typedef A B;
class C : public B {};  // derived from a typedef of X

hasDeclaration()

internal::PolymorphicMatcher< internal::HasDeclarationMatcher, void(internal::HasDeclarationSupportedTypes), internal::Matcher< Decl > > 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>

arrayInitIndexExpr

const internal::VariadicDynCastAllOfMatcher< Stmt, ArrayInitIndexExpr > clang::ast_matchers::arrayInitIndexExpr

The arrayInitIndexExpr consists of two subexpressions: a common expression (the source array) that is evaluated once up-front, and a per-element initializer that runs once for each array element.

Within the per-element initializer, the current index may be obtained via an ArrayInitIndexExpr.

Given

void testStructBinding() {
  int a[2] = {1, 2};
  auto [x, y] = a;
}

arrayInitIndexExpr() matches the array index that implicitly iterates over the array a to copy each element to the anonymous array that backs the structured binding [x, y] elements of which are referred to by their aliases x and y.

• when a lambda-expression captures an array by value
• when a decomposition declaration decomposes an array

Given

void testLambdaCapture() {
  int a[10];
  auto Lam1 = [a]() {
    return;
  };
}

arrayInitLoopExpr() matches the implicit loop that initializes each element of the implicit array field inside the lambda object, that represents the array a captured by value.

binaryOperation

const internal::MapAnyOfMatcher< BinaryOperator, CXXOperatorCallExpr, CXXRewrittenBinaryOperator > clang::ast_matchers::binaryOperation

Matches nodes which can be used with binary operators.

The code

var1 != var2;

might be represented in the clang AST as a binaryOperator, a cxxOperatorCallExpr or a cxxRewrittenBinaryOperator, depending on

• whether the types of var1 and var2 are fundamental (binaryOperator) or at least one is a class type (cxxOperatorCallExpr)
• whether the code appears in a template declaration, if at least one of the vars is a dependent-type (binaryOperator)
• whether the code relies on a rewritten binary operator, such as a spaceship operator or an inverted equality operator (cxxRewrittenBinaryOperator)

This matcher elides details in places where the matchers for the nodes are compatible.

Given

binaryOperation(
  hasOperatorName("!="),
  hasLHS(expr().bind("lhs")),
  hasRHS(expr().bind("rhs"))
)

matches each use of "!=" in:

struct S{

invocation

const internal::MapAnyOfMatcher< CallExpr, CXXConstructExpr > clang::ast_matchers::invocation

Matches function calls and constructor calls.

Because CallExpr and CXXConstructExpr do not share a common base class with API accessing arguments etc, AST Matchers for code which should match both are typically duplicated. This matcher removes the need for duplication.
