class OverloadedMatcherDescriptor
Declaration
class OverloadedMatcherDescriptor : public MatcherDescriptor { /* full declaration omitted */ };
Description
MatcherDescriptor that wraps multiple "overloads" of the same matcher. It will try every overload and generate appropriate errors for when none or more than one overloads match the arguments.

¶void getArgKinds(
clang::ASTNodeKind ThisKind,
unsigned int ArgNo,
std::vector<ArgKind>& Kinds) const
void getArgKinds(
clang::ASTNodeKind ThisKind,
unsigned int ArgNo,
std::vector<ArgKind>& Kinds) const
Description
Given that the matcher is being converted to type \p ThisKind, append the set of argument types accepted for argument \p ArgNo to \p ArgKinds.
Declared at: clang/lib/ASTMatchers/Dynamic/Marshallers.h:777
Parameters
- clang::ASTNodeKind ThisKind
- unsigned int ArgNo
- std::vector<ArgKind>& Kinds
¶unsigned int getNumArgs() const
unsigned int getNumArgs() const
Description
Returns the number of arguments accepted by the matcher if not variadic.
Declared at: clang/lib/ASTMatchers/Dynamic/Marshallers.h:767
¶bool isConvertibleTo(
clang::ASTNodeKind Kind,
unsigned int* Specificity,
clang::ASTNodeKind* LeastDerivedKind) const
bool isConvertibleTo(
clang::ASTNodeKind Kind,
unsigned int* Specificity,
clang::ASTNodeKind* LeastDerivedKind) const
Description
Returns whether this matcher is convertible to the given type. If it is so convertible, store in *Specificity a value corresponding to the "specificity" of the converted matcher to the given context, and in *LeastDerivedKind the least derived matcher kind which would result in the same matcher overload. Zero specificity indicates that this conversion would produce a trivial matcher that will either always or never match. Such matchers are excluded from code completion results.
Declared at: clang/lib/ASTMatchers/Dynamic/Marshallers.h:785
Parameters
- clang::ASTNodeKind Kind
- unsigned int* Specificity
- clang::ASTNodeKind* LeastDerivedKind
¶bool isVariadic() const
bool isVariadic() const
Description
Returns whether the matcher is variadic. Variadic matchers can take any number of arguments, but they must be of the same type.
