Class org.jboss.netty.buffer.ChannelBuffer

Examples of org.jboss.netty.buffer.ChannelBuffer.toByteBuffer()

org.jboss.netty.buffer.ChannelBuffer.toByteBuffer()
Converts this buffer's readable bytes into a NIO buffer. The returned buffer might or might not share the content with this buffer, while they have separate indexes and marks. This method is identical to {@code buf.toByteBuffer(buf.readerIndex(), buf.readableBytes())}.


                    try {
                        final int writeSpinCount = c.getConfig().getWriteSpinCount();
                        boolean sent = false;
                        for (int i = writeSpinCount; i > 0; i --) {
                            ByteBuffer nioBuf = buf.toByteBuffer(bufIdx, buf.writerIndex() - bufIdx);
                            int nioBufSize = nioBuf.remaining();
                            sent = ((WritableMessageChannel) channel).send(nioBuf);
                            if (sent) {
                                bufIdx += nioBufSize;
                                writtenBytes += nioBufSize;
