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.

◆ create()

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

◆ getArgKinds()

void clang::ast_matchers::dynamic::internal::VariadicFuncMatcherDescriptor::getArgKinds ( ast_type_traits::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 420 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 418 of file Marshallers.h.

◆ isConvertibleTo()

bool clang::ast_matchers::dynamic::internal::VariadicFuncMatcherDescriptor::isConvertibleTo ( ast_type_traits::ASTNodeKind  Kind,
unsigned *  Specificity,
ast_type_traits::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.

◆ isVariadic()

bool clang::ast_matchers::dynamic::internal::VariadicFuncMatcherDescriptor::isVariadic ( ) const
inlineoverridevirtual

Returns whether the matcher is variadic.

Variadic matchers can take any number of arguments, but they must be of the same type.
