DANAEVIO UPDATEElliott Wolin

Hall D Offline Meeting6-Apr-2010

DANA -> EVIO conversion 95% complete Handles 20 DANA objects plus ID bank Includes object ID’s for all objects

uint64_t big enough to hold object pointer Includes tagged factories Includes associated objects Includes object ID ↔ name/tag lookup table Easy to add more DANA objects User-supplied XML EVIO tag/num dictionary Everything checked into

XML Dictionary Fragment

Need to change XML

tag name

Associated Object ID bank NOT included if empty only 5 objects have associated object banks

Still missing factory name/tag string array not supported by EVIO yet

Fine for event display development Dave Heddle’s student will work on this

Next step is EVIO -> DANA conversion Dave L (with my help) EVIO format changes unlikely, but possible

Additional uses Transport events over network ???
