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.

◆ pass()

virtual bool fastjet::SelectorWorker::pass ( const PseudoJet jet) const
pure virtual

returns true if a given object passes the selection criterion, and is the main function that needs to be overloaded by derived workers.

NB: this function is used only if applies_jet_by_jet() returns true. If it does not, then derived classes are expected to (re)implement the terminator function()

◆ terminator()

virtual void fastjet::SelectorWorker::terminator ( std::vector< const PseudoJet * > &  jets) const
inlinevirtual

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 argument are not NULL

Definition at line 84 of file Selector.hh.

◆ copy()

virtual SelectorWorker* fastjet::SelectorWorker::copy ( )
inlinevirtual

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 114 of file Selector.hh.

◆ is_geometric()

virtual bool fastjet::SelectorWorker::is_geometric ( ) const
inlinevirtual

check if it is a geometric selector (i.e.

only puts constraints on rapidity and azimuthal angle)
