◆ classof()

static bool llvm::remarks::YAMLRemarkParser::classof ( const RemarkParser * P )

inlinestatic

Definition at line 68 of file YAMLRemarkParser.h.

References P, and llvm::remarks::YAML.

◆ error() [1/2]

Error YAMLRemarkParser::error ( )

protected

Create a YAMLParseError error from an existing error generated by the YAML parser.

If there is no error, this returns Success.

Definition at line 180 of file YAMLRemarkParser.cpp.

References LastErrorMessage, and llvm::Error::success().

Referenced by parseArg(), parseDebugLoc(), parseKey(), parseRemark(), parseStr(), llvm::remarks::YAMLStrTabRemarkParser::parseStr(), parseType(), and parseUnsigned().

◆ error() [2/2]

Error YAMLRemarkParser::error	(	StringRef	Message,
		yaml::Node &	Node
	)

protected

Create a YAMLParseError error referencing a specific node.

Definition at line 176 of file YAMLRemarkParser.cpp.

References SM, and Stream.

◆ next()

Expected< std::unique_ptr< Remark > > YAMLRemarkParser::next ( )

overridevirtual

If no error occurs, this returns a valid Remark object.

If an error of type EndOfFileError occurs, it is safe to recover from it by stopping the parsing. If any other error occurs, it should be propagated to the user. The pointer should never be null.

Implements llvm::remarks::RemarkParser.
