Detailed Description

Simple callback implementation. Marshaller and function are provided.

This class wraps a function of arbitrary signature and a marshaller function into a MatcherDescriptor. The marshaller is in charge of taking the VariantValue arguments, checking their types, unpacking them and calling the underlying function.

Constructor & Destructor Documentation

clang::ast_matchers::dynamic::internal::FixedArgCountMatcherDescriptor::FixedArgCountMatcherDescriptor ( MarshallerType  Marshaller,
void(*)()  Func,
StringRef  MatcherName,
ArrayRef< ast_type_traits::ASTNodeKind RetKinds,
ArrayRef< ArgKind ArgKinds 
)
inline
Parameters
MarshallerFunction to unpack the arguments and call Func
FuncMatcher construct function. This is the function that compile-time matcher expressions would use to create the matcher.
RetKindsThe list of matcher types to which the matcher is convertible.
ArgKindsThe types of the arguments this matcher takes.

Member Function Documentation

VariantMatcher clang::ast_matchers::dynamic::internal::FixedArgCountMatcherDescriptor::create ( const SourceRange NameRange,
ArrayRef< ParserValue Args,

) const
inlineoverridevirtual
void clang::ast_matchers::dynamic::internal::FixedArgCountMatcherDescriptor::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.

unsigned clang::ast_matchers::dynamic::internal::FixedArgCountMatcherDescriptor::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 190 of file Marshallers.h.

bool clang::ast_matchers::dynamic::internal::FixedArgCountMatcherDescriptor::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.

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

bool clang::ast_matchers::dynamic::internal::FixedArgCountMatcherDescriptor::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.
