edm::ObjectWithDict LazyInvoker::invoke	(	const edm::ObjectWithDict &	o,
		std::vector< edm::ObjectWithDict > &	v
	)		const

invoke method, returns object that points to result (after stripping '*' and '&') the object is still owned by the LazyInvoker the actual edm::ObjectWithDict where the result is stored will be pushed in vector so that, if needed, its destructor can be called
