completeExpression() [3/3]

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.

parseExpression() [1/3]

bool clang::ast_matchers::dynamic::Parser::parseExpression ( StringRef &  Code, Sema *  S, const NamedValueMap *  NamedValues, VariantValue *  Value, Diagnostics *  Error  )

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.

parseMatcherExpression() [2/3]

std::optional< DynTypedMatcher > clang::ast_matchers::dynamic::Parser::parseMatcherExpression ( StringRef &  MatcherCode, 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.
