Parameters

hndlObject holding the property value.
docDocumentation string for the property.

This is the version for types that derive from SG::VarHandleBase. The property value object is put on the input and output lists as appropriate; then we forward to the base class.

const SG::NotHandleType &   
)
inlineinherited

Declare a new Gaudi property.

Parameters
nameName of the property.
propertyObject holding the property value.
docDocumentation 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.

)

Declare a new Gaudi property.

Parameters
nameName of the property.
propertyObject holding the property value.

◆ sysInitialize()

virtual StatusCode AthCommonDataStore< AthCommonMsg< AlgTool > >::sysInitialize ( )

Perform system initialization for an algorithm.

We override this to declare all the elements of handle key arrays at the end of initialization. See comments on updateVHKA.

Reimplemented in DerivationFramework::CfAthAlgTool, AthCheckedComponent< AthAlgTool >, AthCheckedComponent<::AthAlgTool >, and asg::AsgMetadataTool.

◆ sysStart()

Handle START transition.

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