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.

	)

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 dispatches to either the generic declareProperty or the one for VarHandle/Key/KeyArray.
