◆ getNumArgs()

virtual unsigned clang::ast_matchers::dynamic::internal::MatcherDescriptor::getNumArgs ( ) const

pure virtual

Returns the number of arguments accepted by the matcher if not variadic.

Implemented in clang::ast_matchers::dynamic::internal::FixedArgCountMatcherDescriptor, clang::ast_matchers::dynamic::internal::VariadicFuncMatcherDescriptor, clang::ast_matchers::dynamic::internal::OverloadedMatcherDescriptor, clang::ast_matchers::dynamic::internal::RegexMatcherDescriptor< ReturnType >, clang::ast_matchers::dynamic::internal::VariadicOperatorMatcherDescriptor, clang::ast_matchers::dynamic::internal::MapAnyOfMatcherDescriptor, and clang::ast_matchers::dynamic::internal::MapAnyOfBuilderDescriptor.

◆ isBuilderMatcher()

virtual bool clang::ast_matchers::dynamic::internal::MatcherDescriptor::isBuilderMatcher ( ) const

Reimplemented in clang::ast_matchers::dynamic::internal::MapAnyOfBuilderDescriptor.

◆ isConvertibleTo()

virtual bool clang::ast_matchers::dynamic::internal::MatcherDescriptor::isConvertibleTo	(	ASTNodeKind	Kind,
		unsigned *	Specificity = `nullptr`,
		ASTNodeKind *	LeastDerivedKind = `nullptr`
	)		const

pure virtual

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.
