howto make CumulativeProtocolDecoder re-entrant

[Vishal_Jain <pi...@gmail.com>]

Hi All,

I noticed that when i have data coming into the decoder as chunks at a fast
rate i.e. before the processing for the first chunk has been completed, it
leads to undesirable results. Since, i don't get time to rewind the buffer
and thus the first buffer is lost. (exception from this is a byproduct;
ProtocolDecoderException: java.nio.BufferUnderflowException)

Earlier i was trying to ascertain if the message received is complete by
parsing for a special sequence (XML tag) by reading each byte in the buffer.
Later, i just converted the message received to a string and checked for the
sequence and accordingly returning true or false. Did manage to get around
the problem, however i don't suppose that this is the best way.

Would someone here have a better solution ?

Thanks in advance,
vishal
