jet::JetIsolation Namespace Reference

Classes
class	IsolationAreaBase
	Defines a zone from which constituents will contribute to the isolation of a jet. More...
class	IsolationCalculator
	IsolationCalculator : base class for isolation calculations Implementations of this class encapsulate all the needed calculations inside the calcIsolationVariables(jet, constituents) function, where 'constituents' is expected to be a vector a consituent NOT containing the jet's constitents.
