Detailed Description

Matcher descriptor interface.

Provides a create() method that constructs the matcher from the provided arguments, and various other methods for type introspection.

buildMatcherCtor()

virtual std::unique_ptr< MatcherDescriptor > clang::ast_matchers::dynamic::internal::MatcherDescriptor::buildMatcherCtor ( SourceRange NameRange, ArrayRef< ParserValue > Args, Diagnostics * Error ) const

create()

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

pure virtual

getArgKinds()

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

pure virtual

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

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.

isBuilderMatcher()

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

inlinevirtual

Definition at line 314 of file Marshallers.h.

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.

isPolymorphic()

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

inlinevirtual

Returns whether the matcher will, given a matcher of any type T, yield a matcher of type T.

Definition at line 349 of file Marshallers.h.

isVariadic()

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

pure virtual

Returns whether the matcher is variadic.

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