I've got a Mina application going that communicates with a variety of
devices through both serial and network interfaces.
Part of this application is data-set simulations (ie fake far-end
devices) handled by using VmPipeAddress and VmPipeConnector objects.
My data simulator puts data into the stream via session.write() calls;
my "normal" decoders pick up that data as if it had come from a real device.
This set of objects works to an extent. BUT.... data that is sent
via two consecutive session.write() calls does NOT show up as expected
in the decoder.
For example, assume a decoder that wants packets delimited by 0x01
(start) and 0xFF (end)
session.write(0x01 02 03 04 05) followed by
session.write(0x06 07 08 09 FF)
Generates two calls to "decode" in the decoder object.
The first with five bytes 0x01 02 03 04 and 05 returns NEED_DATA because
the 0xFF end is not seen
The second with 5 bytes 0x06 07 08 09 FF returns NOT_OK because there is
no 0x01 start byte.
I would have expected two calls, but different parameters:
First with 0x01 02 03 04 05 which would return NEED_DATA.
The second with 0x01 02 03 04 05 06 07 08 09 FF which would return OK
(after parsing) because it had a full packet.
Am I suffering from unrealistic expectations?? Is this a known Mina
bug??? Have I just done something stupid???
Thanks in advance,
boB
