Public Functions Documentation

function clone

virtual unique_ptr< Projection > clone() const =0

Clone on the heap.

Reimplemented by: Rivet::ALICE::V0Multiplicity::clone, Rivet::ALICE::CLMultiplicity::clone, Rivet::ALICE::V0Trigger::clone, Rivet::ALICE::V0AndTrigger::clone, Rivet::ALICE::PrimaryParticles::clone, Rivet::AxesDefinition::clone, Rivet::FastJets::clone, Rivet::ChargedFinalState::clone

function name

inline virtual std::string name() const

Get the name of the projection.

Reimplements: Rivet::ProjectionApplier::name

function valid

inline bool valid() const

Get the state of the projetion.

function failed

inline bool failed() const

Get the state of the projetion.

function before

bool before(
    const Projection & p
) const

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.

function beamPairs

virtual const std::set< PdgIdPair > beamPairs() const

Todo: Remove the beam constraints system from projections.

Return the allowed beam pairs on which this projection can operate, not including recursion. Derived classes should ensure that all contained projections are registered in the _projections set for the beam constraint chaining to work.

function addPdgIdPair

inline Projection & addPdgIdPair(
    PdgId beam1,
    PdgId beam2
)

Todo: This deserves a better name!

Add a colliding beam pair.

function getProjections

inline std::set< ConstProjectionPtr > getProjections() const

Get the contained projections, including recursion.

) const

Does this applier have a projection registered under the name name?

function getProjection

Get the named projection, specifying return type via a template argument.

function getProjection

inline const Projection & getProjection(
    const std::string & name
) const

Get the named projection (non-templated, so returns as a reference to a Projection base class).

function get

template <typename PROJ >
inline const PROJ & get(
    const std::string & name
) const

Todo: Add SFINAE to require that PROJ inherit from Projection

Get the named projection, specifying return type via a template argument (user-facing alias).

function declareProjection

template <typename PROJ >
inline const PROJ & declareProjection(
    const PROJ & proj,
    const std::string & name
)

Register a contained projection.

Todo: Add SFINAE to require that PROJ inherit from Projection

The type of the argument is used to instantiate a new projection internally: this new object is applied to events rather than the argument object. Hence you are advised to only use locally-scoped Projection objects in your Projection and Analysis constructors, and to avoid polymorphism (e.g. handling ConcreteProjection via a pointer or reference to type Projection) since this will screw up the internal type management.

function declare

template <typename PROJ >
inline const PROJ & declare(
