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

llvm::Optional< DynTypedMatcher > clang::ast_matchers::dynamic::Parser::parseMatcherExpression ( StringRef &  MatcherCode,
Sema S,
const NamedValueMap NamedValues,
Diagnostics Error 
)
static

Parse a matcher expression.

Parameters
MatcherCodeThe matcher expression to parse.
SThe Sema instance that will help the parser construct the matchers. If null, it uses the default registry.
NamedValuesA 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.
