Detailed Description

A bigger brother of the MethodInvoker:

• it owns also the object in which to store the result
• it handles by itself the popping out of Refs and Ptrs in this way, it can map 1-1 to a name and set of args

Member Function Documentation

pair< edm::ObjectWithDict, bool > SingleInvoker::invoke	(	const edm::ObjectWithDict &	o,
		std::vector< edm::ObjectWithDict > &	v
	)		const

If the member is found in object o, evaluate and return (value,true) If the member is not found but o is a Ref/RefToBase/Ptr, (return o.get(), false) the actual edm::ObjectWithDict where the result is stored will be pushed in vector so that, if needed, its destructor can be called
