Member Function Documentation

size_t SHMStreamer::operator() ( QDataStream &  stream, CASSEvent &  evt  )

virtual

deserialize stream

Returns

the number of bytes read off the stream

Parameters

stream	The stream that contains the serialized data
evt	The CASS Event that the data should be deserialized to.

read frame header and calculate the frame data size from the contained info. Set the eventid according to the id in the info Then read the frame from the stream into the frame buffer.

get the detector associated with the frame info id from the event

set the information of the frame to the detector

convert the hll type frame to the cass type frame

Todo:

: read out somehow?

Implements cass::TCPStreamer.
