Parameters

name	Name of the property.
hndl	Object holding the property value.
doc	Documentation 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.

Gaudi::Details::PropertyBase* AthCommonDataStore< AthCommonMsg< Algorithm > >::declareProperty ( const std::string &  name, T &  property, const std::string &  doc, const SG::NotHandleType &    )

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

name	Name of the property.
property	Object holding the property value.
