public class MessageWriter
extends java.io.Writer

Combines messages from an OutputStream (hopefully in UTF-8) and a Writer.

This class is primarily meant for BaseConnection in contexts where a standard error stream from a command execution, as well as messages from a side-band channel, need to be combined together into a buffer to represent the complete set of messages from a remote repository.

Writes made to the writer are re-encoded as UTF-8 and interleaved into the buffer that getRawStream() also writes to.

toString() returns all written data, after converting it to a String under the assumption of UTF-8 encoding.

Internally RawParseUtils.decode(byte[]) is used by toString() tries to work out a reasonably correct character set for the raw data.
