◆ actOnMatcherExpression()

VariantMatcher clang::ast_matchers::dynamic::Parser::RegistrySema::actOnMatcherExpression ( MatcherCtor  Ctor,
SourceRange  NameRange,
StringRef  BindID,
ArrayRef< ParserValue Args,
Diagnostics Error 
)
overridevirtual

Process a matcher expression.

All the arguments passed here have already been processed.

Parameters
CtorA matcher constructor looked up by lookupMatcherCtor.
NameRangeThe location of the name in the matcher source. Useful for error reporting.
BindIDThe ID to use to bind the matcher, or a null StringRef if no ID is specified.
ArgsThe argument list for the matcher.
Returns
The matcher objects constructed by the processor, or a null matcher if an error occurred. In that case, Error will contain a description of the error.

◆ getAcceptedCompletionTypes()

std::vector< ArgKind > clang::ast_matchers::dynamic::Parser::RegistrySema::getAcceptedCompletionTypes ( llvm::ArrayRef< std::pair< MatcherCtor, unsigned >>  Context)
overridevirtual

Compute the list of completion types for Context.

Each element of 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.

Reimplemented from clang::ast_matchers::dynamic::Parser::Sema.

◆ getMatcherCompletions()

std::vector< MatcherCompletion > clang::ast_matchers::dynamic::Parser::RegistrySema::getMatcherCompletions ( llvm::ArrayRef< ArgKind AcceptedTypes)
overridevirtual

Compute the list of completions that match any of AcceptedTypes.

Parameters
AcceptedTypesAll types accepted for this completion.
Returns
All completions for the specified types. Completions should be valid when used in lookupMatcherCtor(). The matcher constructed from the return of lookupMatcherCtor() should be convertible to some type in AcceptedTypes.

Reimplemented from clang::ast_matchers::dynamic::Parser::Sema.

◆ lookupMatcherCtor()

llvm::Optional< MatcherCtor > clang::ast_matchers::dynamic::Parser::RegistrySema::lookupMatcherCtor ( StringRef  MatcherName)
overridevirtual

Look up a matcher by name.

Parameters
MatcherNameThe matcher name found by the parser.
Returns
The matcher constructor, or Optional<MatcherCtor>() if not found.
