Detailed Description

This is a helper class to query the version tags from GeoModelSvc and determine the appropriate tag and node to pass to RDBAccessServer.

If a subsystem has an override tag then that tag is used otherwise the ATLAS tag is used.

Constructor & Destructor Documentation

DecodeVersionKey() [1/3]

DecodeVersionKey::DecodeVersionKey	(	const IGeoModelSvc *	geoModel,
		const std::string &	node
	)

Constructor is passed a pointer to GeoModelSvc plus the node for which you want the tag.

Possible nodes are ATLAS, InnerDetector, Pixel, SCT, TRT, LAr, TileCal, or MuonSpectrometer.
