◆ AST_MATCHER() [59/85]

clang::ast_matchers::AST_MATCHER ( ParmVarDecl  ,

Matches a declaration that has default arguments.

Example matches y (matcher = parmVarDecl(hasDefaultArgument()))

void x(int val) {}
void y(int val = 0) {}

Deprecated. Use hasInitializer() instead to be able to match on the contents of the default argument. For example:

void x(int val = 7) {}
void y(int val = 42) {}

parmVarDecl(hasInitializer(integerLiteral(equals(42)))) matches the parameter of y

A matcher such as parmVarDecl(hasInitializer(anything())) is equivalent to parmVarDecl(hasDefaultArgument()).

)

Matches each method overridden by the given method.

This matcher may produce multiple matches.

Given

class B : public A { void f(); };

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".

◆ AST_MATCHER_P() [43/106]

clang::ast_matchers::AST_MATCHER_P ( Expr  ,
ignoringElidableConstructorCall  ,
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).
