public final class ByteWriter

extends java.io.Writer

this writer convers chars to bytes simply by stripping off the high-byte. compatible with ISO-8859-1 only. Like OutputStreamWriter, we use an internal fixed-size byte array to hold conversion output, before we write it to the underlying stream. Unlike OutputStreamWriter, we never hang onto those bytes before writing them through. Thus we never have to worry about clearing the internal buffer, since its contents are never used between subsequent writes.
