    const clang::ast_matchers::dynamic::Parser::
        NamedValueMap* NamedValues,
    clang::ast_matchers::dynamic::Diagnostics*
        Error)

Description

Parse a matcher expression.

Declared at: clang/include/clang/ASTMatchers/Dynamic/Parser.h:184

Parameters

llvm::StringRef& MatcherCode: The matcher expression to parse.
clang::ast_matchers::dynamic::Parser::Sema* S: The Sema instance that will help the parser construct the matchers. If null, it uses the default registry.
const clang::ast_matchers::dynamic::Parser:: NamedValueMap* NamedValues: A map of precomputed named values. This provides the dictionary for the <NamedValue > rule of the grammar. If null, it is ignored.
clang::ast_matchers::dynamic::Diagnostics* Error

Returns

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

    const clang::ast_matchers::dynamic::Parser::
        TokenInfo& NameToken,
    const clang::ast_matchers::dynamic::Parser::

        Value)

Description

Parse and validate a matcher expression.

Declared at: clang/include/clang/ASTMatchers/Dynamic/Parser.h:255

Parameters

const clang::ast_matchers::dynamic::Parser:: TokenInfo& OpenToken
llvm::Optional<MatcherCtor> Ctor
clang::ast_matchers::dynamic::VariantValue* Value

Returns

\c true on success, in which case \c Value has the matcher parsed. If the input is malformed, or some argument has an error, it returns \c false.
