Constructor & Destructor Documentation

FinalState	(	double	mineta = `-MaxRapidity`,
		double	maxeta = `MaxRapidity`,
		double	minpt = `0.0`
	)	`[inline]`

The default constructor. May specify the minimum and maximum pseudorapidity $\eta$ and the min $ p_T $ (in GeV).

Member Function Documentation

Projection& addBeamPair	(	const ParticleName &	beam1,
		const ParticleName &	beam2
	)	`[inline, protected, inherited]`

Add a colliding beam pair.

Definition at line 145 of file Projection.hh.

References Rivet::BeamPair.

Projection& addCut	(	const string &	quantity,
		const Comparison &	comparison,
		const double	value
	)	`[inline, protected, inherited]`

Add a cut.

Definition at line 151 of file Projection.hh.

Projection& addProjection ( Projection & proj ) [inline, protected, inherited]

Add a projection dependency to the projection list.

Definition at line 139 of file Projection.hh.

bool before ( const Projection & p ) const [inline, inherited]

Determine whether this object should be ordered before the object p given as argument. If p is of a different class than this, the before() function of the corresponding type_info objects is used. Otherwise, if the objects are of the same class, the virtual compare(const Projection &) will be returned.

int compare ( const Projection & p ) const [protected, virtual]

Compare projections.

Implements Projection.

Reimplemented in ChargedFinalState, FinalStateHCM, and VetoedFinalState.

virtual const set<BeamPair> getBeamPairs ( ) const [inline, virtual, inherited]

Return the BeamConstraints for this projection. Derived classes should ensure that all contained projections are registered in the _projections set for the beam constraint chaining to work.

Definition at line 114 of file Projection.hh.

References Cuts::end(), and Rivet::intersection().

virtual const Cuts getCuts ( ) const [inline, virtual, inherited]

Return the Cuts objects for this projection. Derived classes should ensure that all contained projections are registered in the _projections set for the cut chaining to work.
