Detailed Description

Interface to connect the parser with the registry and more.

The parser uses the Sema instance passed into parseMatcherExpression() to handle all matcher tokens. The simplest processor implementation would simply call into the registry to create the matchers. However, a more complex processor might decide to intercept the matcher creation and do some extra work. For example, it could apply some transformation to the matcher by adding some id() nodes, or could detect specific matcher nodes for more efficient lookup.

Member Function Documentation

virtual VariantMatcher clang::ast_matchers::dynamic::Parser::Sema::actOnMatcherExpression	(	MatcherCtor	Ctor,
		const SourceRange &	NameRange,
		StringRef	BindID,
		ArrayRef< ParserValue >	Args,
		Diagnostics *	Error
	)		[pure virtual]

Process a matcher expression.

All the arguments passed here have already been processed.

Parameters:

Ctor	A matcher constructor looked up by lookupMatcherCtor.
NameRange	The location of the name in the matcher source. Useful for error reporting.
BindID	The ID to use to bind the matcher, or a null StringRef if no ID is specified.
Args	The 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.

Implemented in clang::ast_matchers::dynamic::Parser::RegistrySema.

std::vector< ArgKind > clang::ast_matchers::dynamic::Parser::Sema::getAcceptedCompletionTypes

(

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

Context

)

[virtual]

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.

std::vector< MatcherCompletion > clang::ast_matchers::dynamic::Parser::Sema::getMatcherCompletions

(

llvm::ArrayRef< ArgKind >

AcceptedTypes

)

[virtual]

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.

virtual llvm::Optional<MatcherCtor> clang::ast_matchers::dynamic::Parser::Sema::lookupMatcherCtor

(

StringRef

MatcherName

)

[pure virtual]

Look up a matcher by name.

Parameters:

MatcherName

The matcher name found by the parser.

Returns:

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

Implemented in clang::ast_matchers::dynamic::Parser::RegistrySema.
