Detailed 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.

create()

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

getArgKinds()

void clang::ast_matchers::dynamic::internal::OverloadedMatcherDescriptor::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 777 of file Marshallers.h.

getNumArgs()

unsigned clang::ast_matchers::dynamic::internal::OverloadedMatcherDescriptor::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 767 of file Marshallers.h.

isConvertibleTo()

bool clang::ast_matchers::dynamic::internal::OverloadedMatcherDescriptor::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.

isVariadic()

bool clang::ast_matchers::dynamic::internal::OverloadedMatcherDescriptor::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.

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