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.

MarshallerType

using clang::ast_matchers::dynamic::internal::FixedArgCountMatcherDescriptor::MarshallerType

Initial value:

 VariantMatcher (*)(void (*Func)(),
                                            StringRef MatcherName,
                                            SourceRange NameRange,

                                            Diagnostics *Error)

Constructor & Destructor Documentation

FixedArgCountMatcherDescriptor()

clang::ast_matchers::dynamic::internal::FixedArgCountMatcherDescriptor::FixedArgCountMatcherDescriptor ( MarshallerType Marshaller, void(* Func )(), StringRef MatcherName, ArrayRef< ASTNodeKind > RetKinds, ArrayRef< ArgKind > ArgKinds )

inline

Parameters

Marshaller	Function to unpack the arguments and call Func
Func	Matcher construct function. This is the function that compile-time matcher expressions would use to create the matcher.
RetKinds	The list of matcher types to which the matcher is convertible.
ArgKinds	The types of the arguments this matcher takes.

Member Function Documentation

create()

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

inlineoverridevirtual

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

Definition at line 394 of file Marshallers.h.

References clang::Error.

getArgKinds()

void clang::ast_matchers::dynamic::internal::FixedArgCountMatcherDescriptor::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 403 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 401 of file Marshallers.h.

isConvertibleTo()

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

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

Definition at line 408 of file Marshallers.h.

References clang::ast_matchers::dynamic::internal::isRetKindConvertibleTo().

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.
