Constructor & Destructor Documentation

BitstreamRemarkParser() [1/2]

llvm::remarks::BitstreamRemarkParser::BitstreamRemarkParser ( StringRef  Buf )

inlineexplicit

Create a parser that expects to find a string table embedded in the stream.

Definition at line 48 of file BitstreamRemarkParser.h.

BitstreamRemarkParser() [2/2]

llvm::remarks::BitstreamRemarkParser::BitstreamRemarkParser ( StringRef  Buf, ParsedStringTable  StrTab  )

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.
