Function Documentation

alignOfExpr()

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

inline

Same as unaryExprOrTypeTraitExpr, but only matching alignof.

Definition at line 2426 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() [6/63]

clang::ast_matchers::AST_MATCHER	(	Decl	,

AST_MATCHER() [7/63]

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())

AST_MATCHER() [8/63]

clang::ast_matchers::AST_MATCHER	(	Expr	,

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

Matches if the call expression's callee expression matches.

void f() { f(); }

callExpr(callee(expr())) matches this->x(), x(), y.x(), f() with callee(...) matching this->x, x, y.x, f respectively

Note: Callee cannot take the more general internal::Matcher<Expr> because this introduces ambiguous overloads with calls to Callee taking a internal::Matcher<Decl>, as the matcher hierarchy is purely implemented in terms of implicit casts.

clang::ast_matchers::AST_MATCHER_P2	(	DeclStmt	,

		InnerMatcher
	)

Matches the n'th declaration of a declaration statement.

Note that this does not work for global declarations because the AST breaks up multiple-declaration DeclStmt's into multiple single-declaration DeclStmt's. Example: Given non-global declarations

int a, b = 0;
int c;
int d = 2, e;

declStmt(containsDeclaration( 0, varDecl(hasInitializer(anything())))) matches only 'int d = 2, e;', and declStmt(containsDeclaration(1, varDecl()))

matches 'int a, b = 0' as well as 'int d = 2, e;'

cxxRecordDecl( has(fieldDecl(hasName("a"), hasType(type().bind("t")))), has(fieldDecl(hasName("b"), hasType(type(equalsBoundNode("t")))))) matches the class X, as a and b have the same type.

Note that when multiple matches are involved via forEach* matchers, equalsBoundNodes acts as a filter. For example: compoundStmt( forEachDescendant(varDecl().bind("d")), forEachDescendant(declRefExpr(to(decl(equalsBoundNode("d")))))) will trigger a match for each combination of variable declaration and reference to that variable declaration within a compound statement.

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:

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>

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.

forEach

const internal::ArgumentAdaptingMatcherFunc< internal::ForEachMatcher > clang::ast_matchers::forEach

Initial value:

=
    {}

Matches AST nodes that have child AST nodes that match the provided matcher.

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
                          // inside Y.
class Z { class Y { class X {}; }; };  // Does not match Z.

ChildT must be an AST base type.

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

forEachDescendant

const internal::ArgumentAdaptingMatcherFunc< internal::ForEachDescendantMatcher > clang::ast_matchers::forEachDescendant = {}

Matches AST nodes that have descendant AST nodes that match the provided matcher.

Example matches X, A, A::X, B, B::C, B::C::X (matcher = cxxRecordDecl(forEachDescendant(cxxRecordDecl(hasName("X")))))

class X {};
class A { class X {}; };  // Matches A, because A::X is a class of name
                          // X inside A.
class B { class C { class 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 {}; }; }; }; };
