Constructor & Destructor Documentation

DISKinematics	(	Beam &	beamp,
		DISLepton &	leptonp,
		const ParticleName &	hadid
	)	`[inline]`

The default constructor. Must specify Beam and DISLepton projection objects which are guaranteed to live throughout the run. Also the PDG code of the incoming hadron (hadid) must be specified.

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

Add a colliding beam pair.

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 with other projections.

Implements Projection.
