Detailed Description

This is a Athena service which manages detector description tag information. It maintains a TagInfo object in the Detector Store with current tag values.

The tags to fill the TagInfo object may come from a variety of sources: i.e. the tags specified by the GeoModelSvc and IOVDbSvc, or the tags stored in the incoming EventInfo object, or the TagInfo object itself may be in the IOV DB. The TagInfoMgr itself only adds in tags from the incoming event. Others are added by external clients.

The interface provides a 'input' method to allow client to add in their own tags:

virtual StatusCode addTag(const std::string& tagName, const std::string& tagValue) = 0;

The full set of tags in TagInfo are copied each event into EventInfo (specifically EventType) to be written out in the event stream. Currently, the tags are NOT written to the IOV DB via the TagInfoMgr.

handle()

void TagInfoMgr::handle ( const Incident &  incident )

finaloverride

This method is called at the both the BeginRun and BeginInputFile incidents:

1) For the first begin run, we retrieve the TagInfo and set up IOVDbSvc so that is can use TagInfo to define its hierarchical tags. The member m_currentRun is saved to be used for the IOV in fillMetaData.

2) Then whenever a new file is opened (BeginInputFile), we use the TagInfo object from the detector store to "re-fill" and overwrite the newly merged TagInfo meta data in the output meta data store. We receive BeginInputFile AFTER the IOVDbMetaDataTool has done this automatic merging, so that we can safely overwrite with the desired TagInfo information for this job/run. As well, if there is a second BeginRun during the processing, here we update m_currentRun and overwrite again the TagInfo in the
meta store with the new run which will just extend the IOV of the TagInfo meta data.
