Classes
class	Jet
	Basic data class defines behavior for all Jet objects The Jet class is the principal data class for all reconstructed jets, independent of the signal course. It describes a navigable composite reconstruction objects with with a four-momentum representation consistent with all other reconstruction objects. Its constituents are referenced as generic INavigable4Momentum types. More...
