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

io.netty.buffer.ByteBuf.readBytes()
Transfers this buffer's data to a newly created buffer starting at the current {@code readerIndex} and increases the {@code readerIndex}by the number of the transferred bytes (= {@code length}). The returned buffer's {@code readerIndex} and {@code writerIndex} are{@code 0} and {@code length} respectively. @param length the number of bytes to transfer @return the newly created buffer which contains the transferred bytes @throws IndexOutOfBoundsException if {@code length} is greater than {@code this.readableBytes}
