Member Function Documentation

std::vector< MatcherCompletion > clang::ast_matchers::dynamic::Parser::completeExpression	(	StringRef	Code,
		unsigned	CompletionOffset,
		Sema *	S,
		const NamedValueMap *	NamedValues
	)		[static]

Complete an expression at the given offset.

Parameters:

S	The Sema instance that will help the parser construct the matchers. If null, it uses the default registry.
NamedValues	A map of precomputed named values. This provides the dictionary for the <NamedValue> rule of the grammar. If null, it is ignored.

Returns:

The list of completions, which may be empty if there are no available completions or if an error occurred.

		const NamedValueMap *	NamedValues,

	)		[static]

Parse an expression.

Parses any expression supported by this parser. In general, the parseMatcherExpression function is a better approach to get a matcher object.

Parameters:

S	The Sema instance that will help the parser construct the matchers. If null, it uses the default registry.
NamedValues	A map of precomputed named values. This provides the dictionary for the <NamedValue> rule of the grammar. If null, it is ignored.

		Sema *	S,
		const NamedValueMap *	NamedValues,
		Diagnostics *	Error
	)		[static]

Parse a matcher expression.

Parameters:

MatcherCode	The matcher expression to parse.
S	The Sema instance that will help the parser construct the matchers. If null, it uses the default registry.
NamedValues	A map of precomputed named values. This provides the dictionary for the <NamedValue> rule of the grammar. If null, it is ignored.

Returns:

The matcher object constructed by the processor, or an empty Optional if an error occurred. In that case, Error will contain a description of the error. The caller takes ownership of the DynTypedMatcher object returned.
