org.fusesource.hawtbuf.proto.CodedOutputStream
public final class CodedOutputStream
Encodes and writes protocol message fields.
This class contains two kinds of methods: methods that write specific
protocol message constructs and field types (e.g. writeTag(int, int)
and
writeInt32(int, int)
) and methods that write low-level values (e.g.
writeRawVarint32(int)
and writeRawBytes(byte[])
). If you are writing
encoded protocol messages, you should use the former methods, but if you are
writing some other format of your own design, use the latter.
This class is totally unsynchronized.
