Re: [xSocket-develop] nbc and reading incomming frames with bytes

[Gregor R. <gre...@go...>]

Hi,

ByteBuffer[] is a reference to an array. To print it out you can use the
DataConverter.toString(Bytebuffer[])  method. Please note, after printing
the data to buffer internal pointers will will modified.

If you like to use a String instead of ByteBuffer you can call the
readStringByLength(available) instead of readByteBufferByLength(available).
