Detailed Description

template<typename Particle>
class KVTemplateEvent< Particle >

Base class for event classes (containers for different types of particle objects)

Template Parameters

Particle Class used to describe particles belonging to the event: must derive from KVParticle

An event is a container for a collection of objects representing massive particles (derived from KVParticle): Particles are added to an event using methods AddParticle() or AddNucleus(). The first method returns a pointer to the added particle which is of the same type as the particle objects contained in the event, while the latter casts the pointer to KVNucleus* for classes which derive from KVNucleus, returning nullptr if not (but a particle is still created and added to the event):

KVTemplateEvent<KVParticle> part_event;
KVTemplateEvent<KVReconstructedNucleus> recon_event;
 
auto p = part_event.AddParticle(); // KVParticle* p
auto n = part_event.AddNucleus(); // KVNucleus* n == nullptr
 
auto r = recon_event.AddParticle(); // KVReconstructedNucleus* r
auto s = recon_event.AddNucleus(); // KVNucleus* s == r

Particles in events can be iterated over using range-based for loops:

KVTemplateEvent<KVParticle> part_event;
for(auto& p : part_event) std::cout << p.GetMass() << std::endl; // p is type KVParticle&
 
KVTemplateEvent<KVReconstructedNucleus> recon_event;
for(auto& r : recon_event) if(r.IsAMeasured()) std::cout << r.GetRealA() << std::endl; // r is type KVReconstructedNucleus&

Note: that in such event loops, you should always use a reference to access each particle of the event as shown in these examples.

The iteration can be limited to only a subset of particles in the event using arbitrary particle selections (see KVTemplateParticleCondition):

KVTemplateEvent<KVReconstructedNucleus> recon_event;
int ztot=0;
for(auto& p : recon_event.ConditionalIterator({"IDZ", [](const KVReconstructedNucleus* n){ return n->IsZMeasured(); }}))
   ztot += p.GetZ();

For a full description of event iterators, see Iterating over nuclei in the Users Guide.

	)

inline

Fill histogram with values of the observable given by the indicated Nucleus_method. For example: if the method is called this way - FillHisto(h,"GetZ") - it fills histogram with the charge of all particles in the current event.

inline

Clear & fill the KVIntegerList with the contents of this event, the option will be passed to GetNextParticle(opt). IntegerList is then 'Update()'d. (This method was originally KVIntegerList::Fill(KVEvent*,Option_t*), it was moved here in order to make KVIntegerList a base class)

◆ GetMultiplicity()

template<typename Particle >

Int_t KVTemplateEvent< Particle >::GetMultiplicity	(	Int_t	Z,
		Int_t	A = `0`,
		Option_t *	opt = `""`
	)

inline

Calculate the multiplicity of nuclei given Z (if A not given) or of nuclei with given Z & A (if given)

If opt = "ok" only particles with IsOK()==kTRUE are considered. If opt = "name" only particles belonging to group "name" are considered.

Definition at line 416 of file KVTemplateEvent.h.

◆ GetNextParticle()

template<typename Particle >

Particle * KVTemplateEvent< Particle >::GetNextParticle ( Option_t * opt = "" ) const

inlinevirtual

Use this method to iterate over the list of nuclei in the event After the last particle GetNextNucleus() returns a null pointer and resets itself ready for a new iteration over the particle list.

If opt="" all particles are included in the iteration. If opt="ok" or "OK" only nuclei whose KVNucleus::IsOK() method returns kTRUE are included.

Any other value of opt is interpreted as a (case-insensitive) particle group name: only particles with BelongsToGroup(opt) returning kTRUE are included.

If you want to start from the beginning again before getting to the end of the list, especially if you want to change the selection criteria, call method ResetGetNextNucleus() before continuing.

If you interrupt an iteration before the end, then start another iteration without calling ResetGetNextNucleus(), even if you change the argument of the call to GetNextNucleus(), you will repeat exactly the same iteration as the previous one.

Warning: Only one iteration at a time over the event can be performed using this method. If you want/need to perform several i.e. nested iterations, use the Iterator KVTemplateEvent::EventIterator

continue iteration

start new iteration

◆ GetNextParticleIterator()

template<typename Particle >

Iterator KVTemplateEvent< Particle >::GetNextParticleIterator ( Option_t * opt ) const

inline

Provide correct iterator using same options as for GetNextParticle() method:

if opt="" (default) => iterator over all particles
if opt="ok"/"OK" => iterator for all "OK" particles
if opt!="" && opt!="ok"/"OK" => iterator for all particles in group with name given by opt (case-insensitive)

Double_t KVTemplateEvent< Particle >::GetSum	(	const Char_t *	Nucleus_method,
		const Char_t *	method_prototype,
		const Char_t *	args,
		Option_t *	opt = `""`
	)

inline

Returns sum over particles of the observable given by the indicated Nucleus_method with given prototype (e.g. method_prototype="int,int") and argument values e.g. args="2,4")

If opt = "ok" only particles with IsOK()==kTRUE are considered. If opt = "name" only particles belonging to group "name" are considered.

Definition at line 486 of file KVTemplateEvent.h.

◆ GetSum() [2/2]

template<typename Particle >

Double_t KVTemplateEvent< Particle >::GetSum	(	const Char_t *	Nucleus_method,
		Option_t *	opt = `""`
	)

inlinevirtual

Returns sum over particles of the observable given by the indicated Nucleus_method for example if the method is called this way GetSum("GetZ"), it returns the sum of the charge of particles in the current event

If opt = "ok" only particles with IsOK()==kTRUE are considered. If opt = "name" only particles belonging to group "name" are considered.

◆ Print()

template<typename Particle >

virtual void KVTemplateEvent< Particle >::Print ( Option_t * t = "" ) const

inlinevirtual

Print a list of all particles in the event with some characteristics. Optional argument t can be used to select particles (="ok", "groupname", ...)

◆ ResetEnergies()

template<typename Particle >

void KVTemplateEvent< Particle >::ResetEnergies ( )

inline

Used for simulated events after "detection" by some multidetector array.

The passage of the event's particles through the different absorbers modifies their kinetic energies, indeed all those which are correctly identified by the detector actually stop. Calling this method will reset all the particles' energies to their initial value i.e. before they entered the first absorber. Particles which have not encountered any absorbers/detectors are left as they are.

Definition at line 676 of file KVTemplateEvent.h.

◆ ResetGetNextParticle()

template<typename Particle >

void KVTemplateEvent< Particle >::ResetGetNextParticle ( ) const

inlinevirtual

Reset iteration over event particles so that next call to GetNextParticle will begin a new iteration (possibly with different criteria).

◆ SetFrame() [1/2]

template<typename Particle >

void KVTemplateEvent< Particle >::SetFrame	(	const Char_t *	frame,
		const KVFrameTransform &	ft
	)

inlinevirtual

Define a Lorentz-boosted and/or rotated frame for all particles in the event. See KVParticle::SetFrame() for details.

In order to access the kinematics in the boosted frame, use the GetFrame() method of the individual particles (see KVParticle::GetFrame()).

Implements KVEvent.

◆ SetFrame() [2/2]

template<typename Particle >

void KVTemplateEvent< Particle >::SetFrame	(	const Char_t *	newframe,

inlinevirtual

Define a Lorentz-boosted frame "newframe" for all particles in the event. The transformation is applied to the particle coordinates in the existing frame "oldframe"

See KVParticle::SetFrame() for details.

In order to access the kinematics in the boosted frame, use the GetFrame() method of the individual particles in either of these ways : KVParticle* newframe = particle->GetFrame("newframe"); KVParticle* newframe = particle->GetFrame("oldframe")->GetFrame("newframe");

Implements KVEvent.

Definition at line 725 of file KVTemplateEvent.h.

◆ SetFrameName()

template<typename Particle >

void KVTemplateEvent< Particle >::SetFrameName ( const KVString & name )

inlinevirtual

◆ UpdateAllFrames()
