Loop through all output handles, and if they're WriteCondHandles, automatically register them and this Algorithm with the CondSvc

Scan through all outputHandles, and if they're WriteCondHandles, register them with the CondSvc

Reimplemented from AthCommonDataStore< AthCommonMsg< Algorithm > >.

Reimplemented in AthAnalysisAlgorithm, AthFilterAlgorithm, AthHistogramAlgorithm, and PyAthena::Alg.

◆ sysStart()

virtual StatusCode AthCommonDataStore< AthCommonMsg< Algorithm > >::sysStart ( )

Handle START transition.

We override this in order to make sure that conditions handle keys can cache a pointer to the conditions container.
