How to use

BufferOutputStream

in

ch.cyberduck.core.io

@Override
public void write(byte[] buffer) throws IOException {
  this.write(buffer, 0, buffer.length);
}

public BufferSegmentingOutputStream(final OutputStream proxy, final Long threshold, final Buffer buffer) {
  super(new NullOutputStream(), threshold, new BufferOutputStream(buffer));
  this.proxy = proxy;
  this.buffer = buffer;
}

  @Override
  public void close() throws IOException {
    try {
      // Reset offset in transfer status because data was already streamed
      // through StreamCopier when writing to buffer
      final TransferStatus range = new TransferStatus(status).length(buffer.length()).append(false);
      if(0L == buffer.length()) {
        new GraphTouchFeature(session).touch(file, new TransferStatus());
      }
      else {
        final HttpResponseOutputStream<Void> out = new GraphWriteFeature(session).write(file,
          range, callback);
        IOUtils.copy(new BufferInputStream(buffer), out);
        out.close();
        log.info(String.format("Completed upload for %s with status %s", file, range));
      }
      super.close();
    }
    catch(BackgroundException e) {
      throw new IOException(e);
    }
  }
}) {
