Class PacketLineOut


  • public class PacketLineOut
    extends Object
    Write Git style pkt-line formatting to an output stream.

    This class is not thread safe and may issue multiple writes to the underlying stream for each method call made.

    This class performs no buffering on its own. This makes it suitable to interleave writes performed by this class with writes performed directly against the underlying OutputStream.

    • Constructor Detail

      • PacketLineOut

        public PacketLineOut​(OutputStream outputStream)
        Create a new packet line writer.
        Parameters:
        outputStream - stream.
    • Method Detail

      • setFlushOnEnd

        public void setFlushOnEnd​(boolean flushOnEnd)
        Set the flush behavior during end().
        Parameters:
        flushOnEnd - if true, a flush-pkt written during end() also flushes the underlying stream.
      • writeString

        public void writeString​(String s)
                         throws IOException
        Write a UTF-8 encoded string as a single length-delimited packet.
        Parameters:
        s - string to write.
        Throws:
        IOException - the packet could not be written, the stream is corrupted as the packet may have been only partially written.
      • writePacket

        public void writePacket​(byte[] packet)
                         throws IOException
        Write a binary packet to the stream.
        Parameters:
        packet - the packet to write; the length of the packet is equal to the size of the byte array.
        Throws:
        IOException - the packet could not be written, the stream is corrupted as the packet may have been only partially written.
      • end

        public void end()
                 throws IOException
        Write a packet end marker, sometimes referred to as a flush command.

        Technically this is a magical packet type which can be detected separately from an empty string or an empty packet.

        Implicitly performs a flush on the underlying OutputStream to ensure the peer will receive all data written thus far.

        Throws:
        IOException - the end marker could not be written, the stream is corrupted as the end marker may have been only partially written.
      • flush

        public void flush()
                   throws IOException
        Flush the underlying OutputStream.

        Performs a flush on the underlying OutputStream to ensure the peer will receive all data written thus far.

        Throws:
        IOException - the underlying stream failed to flush.
