Function Documentation

◆ alignOfExpr()

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

Same as unaryExprOrTypeTraitExpr, but only matching alignof.

Definition at line 2961 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

Definition at line 169 of file ASTMatchers.h.

◆ AST_MATCHER() [1/74]

clang::ast_matchers::AST_MATCHER ( CallExpr  ,

)

Matches call expressions which were resolved using ADL.

Example matches y(x) but not y(42) or NS::y(x).

namespace NS {
struct X {};
void y(X);
}
void y(...);
void test() {
y(x); // Matches
NS::y(x); // Doesn't match
y(42); // Doesn't match
using NS::y;
y(x); // Found by both unqualified lookup and ADL, doesn't match

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".

clang::ast_matchers::AST_MATCHER_P ( Expr  ,
ignoringElidableConstructorCall  ,
ast_matchers::internal::Matcher< Expr ,
InnerMatcher   
)

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).

Matches a node if it equals the node previously bound to ID.

Given
