class OverloadedMatcherDescriptor

Declaration

class OverloadedMatcherDescriptor : public MatcherDescriptor { /* full declaration omitted */ };

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.

Methods

¶OverloadedMatcherDescriptor(
    MutableArrayRef<
        std::unique_ptr<MatcherDescriptor>>
        Callbacks)

Declared at: clang/lib/ASTMatchers/Dynamic/Marshallers.h:727

Parameters

MutableArrayRef< std::unique_ptr<MatcherDescriptor>> Callbacks

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

Declared at: clang/lib/ASTMatchers/Dynamic/Marshallers.h:734

Parameters

clang::ast_matchers::dynamic::SourceRange NameRange

ArrayRef< clang::ast_matchers::dynamic::ParserValue> Args

clang::ast_matchers::dynamic::Diagnostics* Error

¶void getArgKinds(
    clang::ASTNodeKind ThisKind,
    unsigned int ArgNo,
    std::vector<ArgKind>& Kinds) const

Description

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

Declared at: clang/lib/ASTMatchers/Dynamic/Marshallers.h:777

Parameters

clang::ASTNodeKind ThisKind

unsigned int ArgNo

std::vector<ArgKind>& Kinds

¶unsigned int getNumArgs() const

Description

Returns the number of arguments accepted by the matcher if not variadic.

Declared at: clang/lib/ASTMatchers/Dynamic/Marshallers.h:767

¶bool isConvertibleTo(
    clang::ASTNodeKind Kind,
    unsigned int* Specificity,
    clang::ASTNodeKind* LeastDerivedKind) const

Description

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.

Declared at: clang/lib/ASTMatchers/Dynamic/Marshallers.h:785

Parameters

clang::ASTNodeKind Kind

unsigned int* Specificity

clang::ASTNodeKind* LeastDerivedKind

¶bool isVariadic() const

Description

Returns whether the matcher is variadic. Variadic matchers can take any number of arguments, but they must be of the same type.
