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

◆ FixedArgCountMatcherDescriptor()

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.

◆ create()

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

◆ getArgKinds()

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.

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

Definition at line 262 of file Marshallers.h.

◆ getNumArgs()

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 260 of file Marshallers.h.

◆ isConvertibleTo()

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.

◆ isVariadic()

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.
