Member Function Documentation

hasError()

bool llvm::lsp::JSONTransportInputOverFile::hasError ( ) const

inlinefinalvirtual

Implements llvm::lsp::JSONTransportInput.

Definition at line 81 of file Transport.h.

References const.

Referenced by readStandardMessage().

isEndOfInput()

bool llvm::lsp::JSONTransportInputOverFile::isEndOfInput ( ) const

inlinefinalvirtual

Implements llvm::lsp::JSONTransportInput.

Definition at line 82 of file Transport.h.

References const.

readDelimitedMessage()

LogicalResult JSONTransportInputOverFile::readDelimitedMessage ( std::string & Json )

finalvirtual

For lit tests we support a simplified syntax:

• messages are delimited by '// --—' on a line by itself
• lines starting with // are ignored. This is a testing path, so favor simplicity over performance here. When returning failure: feof(), ferror(), or shutdownRequested() will be set.
