inlineinherited

Declare a new Gaudi property.

Parameters

name	Name of the property.
property	Object holding the property value.
doc	Documentation string for the property.

This is the generic version, for types that do not derive from SG::VarHandleKey. It just forwards to the base class version of declareProperty.

Parameters

sysExecute()

StatusCode AthCommonReentrantAlgorithm< Gaudi::Algorithm >::sysExecute ( const EventContext &  ctx )

Execute an algorithm.

We override this in order to work around an issue with the Algorithm base class storing the event context in a member variable that can cause crashes in MT jobs.

sysInitialize()

Override sysInitialize.

Override sysInitialize from the base class.

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< Gaudi::Algorithm > >.
