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 std::string & name
) const

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

function getProjection ##

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

function getProjection ##

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

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(
    const PROJ & proj,
    const std::string & name
)

Register a contained projection (user-facing version)

function declare ##

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

Todo: Add SFINAE to require that PROJ inherit from Projection

function project ##

inline virtual void project(
    const Event & e
)

Reimplements: Rivet::AxesDefinition::project

Take the information available in the Event and make the calculations necessary to obtain the projection. Note that this function must never be called except inside the Event::applyProjection(Projection *) function.

function compare ##

inline virtual CmpState compare(
    const Projection & p
) const

Reimplements: Rivet::AxesDefinition::compare

This function is used to define a unique ordering between different Projection objects of the same class. If this is considered to be equivalent to the Projector object, p, in the argument the function should return 0. If this object should be ordered before p a negative value should be returned, otherwise a positive value should be returned. This function must never be called explicitly, but should only be called from the operator<(const Projection &). When implementing the function in concrete sub-classes, it is then guaranteed that the Projection object p in the argument is of the same class as the sub-class and can be safely dynamically casted to that class.

When implementing this function in a sub-class, the immediate base class version of the function should be called first. If the base class function returns a non-zero value, that value should be returned immediately. Only if zero is returned should this function check the member variables of the sub-class to determine whether this should be ordered before or after p, or if it is equivalent with p.

function setValue ##

inline void setValue(
    double v
)

Set the value.

function set ##

inline void set(
    double v

Deprecated:

Less clear alias

function clear ##

inline void clear()
