diff()

void diff	(	const TrigVertex &	a,
		const TrigVertex &	b,
		std::map< std::string, double > &	variableChange )

comparison with feedback Function compares two objects and returns "semi verbose" output in the form of map where there are varaibel names and differences between two obejcts

Parameters

variableChange

- map to record the differences In case of collections (or objects when the size may be different) that information can also be returned in variableChange
