Detailed Description

Classes derived from the SelectorBase class are used to extract particles from an Event with Event::select() method.

There are five different kinds of checks done by a selector object in the Event::select method. If the allCollisions() method returns false, only particles which belongs to the primary collision in an event will be considered for extraction. Furthermore if the allSteps() method returns false, only particles present in the final step of each collision will be considered. If finalState() returns false, final state particles will not be considered and if intermediate() returns false, intermediate particles will not be considered. Finally among all considered particles, only the ones for which the check(const Particle &) returns true will be extracted.
