Detailed Description

default selector worker is an abstract virtual base class

The Selector class is only an interface, it is the SelectorWorker that really does the work. To implement various selectors, one thus has to overload this class.

Member Function Documentation

virtual bool fastjet::SelectorWorker::pass

(

const PseudoJet &

jet

)

const [pure virtual]

returns true if a given object passes the selection criterion.

This has to be overloaded by derived workers

virtual void fastjet::SelectorWorker::terminator

(

std::vector< const PseudoJet * > &

jets

)

const [inline, virtual]

For each jet that does not pass the cuts, this routine sets the pointer to 0.

It does not assume that the PseudoJet* passed as argumetn are not NULL

Definition at line 77 of file Selector.hh.

                                                                     {
    for (unsigned i = 0; i < jets.size(); i++) {
      if (jets[i] && !pass(*jets[i])) jets[i] = NULL;
    }
  }

virtual SelectorWorker* fastjet::SelectorWorker::copy

(

)

[inline, virtual]

return a copy of the current object.

This function is only called for objects that take a reference and need not be reimplemented otherwise.

Definition at line 105 of file Selector.hh.

                                { 
    throw Error("this SelectorWorker has nothing to copy");
  }
