Examples of io.netty.buffer.ByteBuf.writeInt()

io.netty.buffer.ByteBuf.writeInt()
Sets the specified 32-bit integer at the current {@code writerIndex}and increases the {@code writerIndex} by {@code 4} in this buffer. @throws IndexOutOfBoundsException if {@code this.writableBytes} is less than {@code 4}

      int messageLength = message == null ? 0 : message.readableBytes();


      // Build message header
      ByteBuf headerBuf = channel.alloc().buffer(headerLength);
      headerBuf.writeInt(MESSAGE_VERSION).writeInt(messageType)
          .writeLong(messageId.getMostSignificantBits())
