Detailed Description

Matcher descriptor for variadic functions.

This class simply wraps a VariadicFunction with the right signature to export it as a MatcherDescriptor. This allows us to have one implementation of the interface for as many free functions as we want, reducing the number of symbols and size of the object file.

Member Function Documentation

◆ create()

VariantMatcher clang::ast_matchers::dynamic::internal::VariadicFuncMatcherDescriptor::create	(	SourceRange	NameRange,
		ArrayRef< ParserValue >	Args,
		Diagnostics *	Error
	)		const

inlineoverridevirtual

Implements clang::ast_matchers::dynamic::internal::MatcherDescriptor.

◆ getArgKinds()

void clang::ast_matchers::dynamic::internal::VariadicFuncMatcherDescriptor::getArgKinds	(	ASTNodeKind	ThisKind,
		unsigned	ArgNo,
		std::vector< ArgKind > &	ArgKinds
	)		const

inlineoverridevirtual

Given that the matcher is being converted to type ThisKind, append the set of argument types accepted for argument ArgNo to ArgKinds.

Implements clang::ast_matchers::dynamic::internal::MatcherDescriptor.

Definition at line 568 of file Marshallers.h.

◆ getNumArgs()

unsigned clang::ast_matchers::dynamic::internal::VariadicFuncMatcherDescriptor::getNumArgs ( ) const

inlineoverridevirtual

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

Implements clang::ast_matchers::dynamic::internal::MatcherDescriptor.

Definition at line 566 of file Marshallers.h.

◆ isConvertibleTo()

bool clang::ast_matchers::dynamic::internal::VariadicFuncMatcherDescriptor::isConvertibleTo	(	ASTNodeKind	Kind,
		unsigned *	Specificity,
		ASTNodeKind *	LeastDerivedKind
	)		const

inlineoverridevirtual

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.
