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

io.netty.buffer.ByteBuf.writeBytes()
Transfers the specified source buffer's data to this buffer starting at the current {@code writerIndex} until the source buffer becomesunreadable, and increases the {@code writerIndex} by the number ofthe transferred bytes. This method is basically same with {@link #writeBytes(ByteBuf,int,int)}, except that this method increases the {@code readerIndex} of the source buffer by the number ofthe transferred bytes while {@link #writeBytes(ByteBuf,int,int)}does not. @throws IndexOutOfBoundsException if {@code src.readableBytes} is greater than{@code this.writableBytes}
