buildMatcherCtor()

internal::MatcherDescriptorPtr clang::ast_matchers::dynamic::Registry::buildMatcherCtor ( MatcherCtor  Ctor, SourceRange  NameRange, ArrayRef< ParserValue >  Args, Diagnostics *  Error  )

static

Definition at line 633 of file Registry.cpp.

References clang::ast_matchers::dynamic::internal::MatcherDescriptor::buildMatcherCtor().

constructBoundMatcher()

VariantMatcher clang::ast_matchers::dynamic::Registry::constructBoundMatcher ( MatcherCtor  Ctor, SourceRange  NameRange, StringRef  BindID, ArrayRef< ParserValue >  Args, Diagnostics *  Error  )

static

Construct a matcher from the registry and bind it.

Similar the constructMatcher() above, but it then tries to bind the matcher to the specified BindID. If the matcher is not bindable, it sets an error in Error and returns a null matcher.

constructMatcher()

VariantMatcher clang::ast_matchers::dynamic::Registry::constructMatcher ( MatcherCtor  Ctor, SourceRange  NameRange, ArrayRef< ParserValue >  Args, Diagnostics *  Error  )

static

Construct a matcher from the registry.

Parameters

Ctor	The matcher constructor to instantiate.
NameRange	The location of the name in the matcher source. Useful for error reporting.
Args	The argument list for the matcher. The number and types of the values must be valid for the matcher requested. Otherwise, the function will return an error.

Returns

The matcher object constructed if no error was found. A null matcher if the number of arguments or argument types do not match the signature. In that case Error will contain the description of the error.

getAcceptedCompletionTypes()

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

static

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.

getMatcherCompletions()

std::vector< MatcherCompletion > clang::ast_matchers::dynamic::Registry::getMatcherCompletions ( ArrayRef< ArgKind >  AcceptedTypes )

static

Compute the list of completions that match any of AcceptedTypes.

Parameters

AcceptedTypes

All 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.

lookupMatcherCtor()

std::optional< MatcherCtor > clang::ast_matchers::dynamic::Registry::lookupMatcherCtor ( StringRef  MatcherName )

static

Look up a matcher in the registry by name,.

Returns

An opaque value which may be used to refer to the matcher constructor, or std::optional<MatcherCtor>() if not found.
