edm::ObjectWithDict MethodInvoker::invoke	(	const edm::ObjectWithDict &	obj,
		edm::ObjectWithDict &	retstore
	)		const

Invokes the method, putting the result in retval. Returns the Object that points to the result value, after removing any "*" and "&" Caller code is responsible for allocating retstore before calling 'invoke', and of deallocating it afterwards
