The structure for a jet made of pieces.
This stores the vector of the pieces that make the jet and provide the methods to access them

| std::vector< PseudoJet > fastjet::CompositeJetStructure::constituents | ( | const PseudoJet & | jet | ) | const [virtual] |
return the constituents (i.e.
the union of the constituents of each piece)
If any of the pieces has no constituent, the piece itself is considered as a constituent Note that as a consequence, a composite jet with no pieces will have an empty vector as constituents

| double fastjet::CompositeJetStructure::area_error | ( | const PseudoJet & | reference | ) | const [virtual] |
return the error (uncertainty) associated with the determination of the area of this jet.
Be conservative: return the sum of the errors

| bool fastjet::CompositeJetStructure::is_pure_ghost | ( | const PseudoJet & | reference | ) | const [virtual] |
true if this jet is made exclusively of ghosts.
In this case, it will be true if all pieces are pure ghost
