Detailed Description

Definitions for an ISIS Event Stream

Author

Freddie Akeroyd, STFC ISIS Facility, GB

The stream is a sequence of TCPStreamEventHeader followed by the appropriate data for that header type For neutron event data this is all described in TCPStreamEventDataNeutron etc

The data is generated in TCPEventStreamConnection::allEventCallback() and then spooled to clients in TCPEventStreamConnection::run() See EventsToolApp::liveData() in events_tool.cpp for a client example
