        Ctor,

        Args,
    clang::ast_matchers::dynamic::Diagnostics*
        Error)

Description

Process a matcher expression. All the arguments passed here have already been processed.

Declared at: clang/include/clang/ASTMatchers/Dynamic/Parser.h:144

Parameters

clang::ast_matchers::dynamic::MatcherCtor Ctor
A matcher constructor looked up by lookupMatcherCtor.
clang::ast_matchers::dynamic::SourceRange NameRange
The location of the name in the matcher source. Useful for error reporting.
llvm::StringRef BindID
The ID to use to bind the matcher, or a null \c StringRef if no ID is specified.
ArrayRef< clang::ast_matchers::dynamic::ParserValue> Args
The argument list for the matcher.
clang::ast_matchers::dynamic::Diagnostics* Error

Returns

The matcher objects constructed by the processor, or a null matcher if an error occurred. In that case, \c Error will contain a description of the error.

std::vector<ArgKind> getAcceptedCompletionTypes(
    llvm::ArrayRef<
        std::pair<MatcherCtor, unsigned int>>
        Context)

Description

Compute the list of completion types for \p Context. Each element of \p Context represents a matcher invocation, going from outermost to innermost. Elements are pairs consisting of a reference to the matcher constructor and the index of the next element in the argument list of that matcher (or for the last element, the index of the completion point in the argument list). An empty list requests completion for the root matcher.

Declared at: clang/include/clang/ASTMatchers/Dynamic/Parser.h:150

Parameters

llvm::ArrayRef< std::pair<MatcherCtor, unsigned int>> Context

std::vector<MatcherCompletion>
getMatcherCompletions(
    llvm::ArrayRef<ArgKind> AcceptedTypes)

Description

Compute the list of completions that match any of\p AcceptedTypes.

Declared at: clang/include/clang/ASTMatchers/Dynamic/Parser.h:163

Parameters

llvm::ArrayRef<ArgKind> AcceptedTypes
All types accepted for this completion.

Returns

All completions for the specified types. Completions should be valid when used in \c lookupMatcherCtor(). The matcher constructed from the return of \c lookupMatcherCtor() should be convertible to some type in \p AcceptedTypes.

bool isBuilderMatcher(
    clang::ast_matchers::dynamic::MatcherCtor
        Ctor) const

llvm::Optional<MatcherCtor> lookupMatcherCtor(
    llvm::StringRef MatcherName)

Description

Declared at: clang/include/clang/ASTMatchers/Dynamic/Parser.h:142

Parameters

llvm::StringRef MatcherName

Returns

The matcher constructor, or Optional <MatcherCtor >() if not found.
