	)

staticinherited

converts a local hit into sensor-independent relative coordinates.

first parameter is the local hit (as provided by SpacePoint::getUWedged(...) and Cluster::getV!) stored as a pair of doubles. second parameter is the coded vxdID, which carries the sensorID. third parameter, a sensorInfo can be passed for testing purposes. If no sensorInfo is passed, the member gets its own pointer to it.

ATTENTION: this function assumes, that for wedged sensors, the uCoordinate is already adapted to the vCoordinate! The normalized coordinates are independent of wedged-sensor-issues

Definition at line 149 of file SpacePoint.cc.

{
  //We need some handle to translate IDs to local and global
  // coordinates.
  if (aSensorInfo == nullptr) {
    aSensorInfo = &VXD::GeoCache::getInstance().getSensorInfo(vxdID);
  }
 
  //As the 0 is in the middle of sensor in the geometry, and we want
  // to normalize all positions to numbers between [0,1],
  // where the middle will be 0.5,
  // we need to do some calculation.
  double sensorSizeU =  aSensorInfo->getUSize(hitLocal.second); // this deals with the case of trapezoidal sensors too
  double sensorSizeV =  aSensorInfo->getVSize();

		Belle2::VxdID	vxdID,
		const Belle2::VXD::SensorInfoBase *	aSensorInfo = `nullptr`
	)

staticinherited

converts a hit in sensor-independent relative coordinates into local coordinate of given sensor.

first parameter is the hit in sensor-independent normalized ! coordinates stored as a pair of floats. second parameter is the coded vxdID, which carries the sensorID. third parameter, a sensorInfo can be passed for testing purposes. If no sensorInfo is passed, the member gets its own pointer to it.

Definition at line 178 of file SpacePoint.cc.

{
  //We need some handle to translate IDs to local and global
  // coordinates.
  if (aSensorInfo == nullptr) {
    aSensorInfo = &VXD::GeoCache::getInstance().getSensorInfo(vxdID);

                  0, vxdID); // restrain hits to sensor boundaries
 
  return { localUPosition, localVPosition };
}

◆ copyRelations()

void copyRelations ( const RelationsInterface< BASE > * sourceObj )

inlineinherited

Copies all relations of sourceObj (pointing from or to sourceObj) to this object (including weights).

Useful if you want to make a complete copy of a StoreArray object to make modifications to it, but retain all information on linked objects.

Note: this only works if sourceObj inherits from the same base (e.g. RelationsObject), and only for related objects that also inherit from the same base.

Definition at line 170 of file RelationsObject.h.

    {
      if (!sourceObj)
        return;
      auto fromRels = sourceObj->getRelationsFrom<RelationsInterface<BASE>>("ALL");
      for (unsigned int iRel = 0; iRel < fromRels.size(); iRel++) {
        fromRels.object(iRel)->addRelationTo(this, fromRels.weight(iRel));
      }
 
      auto toRels = sourceObj->getRelationsTo<RelationsInterface<BASE>>("ALL");
      for (unsigned int iRel = 0; iRel < toRels.size(); iRel++) {
        this->addRelationTo(toRels.object(iRel), toRels.weight(iRel));
      }
    }

◆ getArrayIndex()

inlineinherited

Returns this object's array index (in StoreArray), or -1 if not found.

Definition at line 385 of file RelationsObject.h.

    {
      DataStore::Instance().findStoreEntry(this, m_cacheDataStoreEntry, m_cacheArrayIndex);
      return m_cacheArrayIndex;
    }

◆ getArrayName()

std::string getArrayName ( ) const

inlineinherited

Get name of array this object is stored in, or "" if not found.

Definition at line 377 of file RelationsObject.h.

    {
      DataStore::Instance().findStoreEntry(this, m_cacheDataStoreEntry, m_cacheArrayIndex);
      return m_cacheDataStoreEntry ? m_cacheDataStoreEntry->name : "";
    }

◆ getArrayPointer()

TClonesArray * getArrayPointer ( ) const

inlineprotectedinherited

Returns the pointer to the raw DataStore array holding this object (protected since these arrays are easy to misuse).

Definition at line 418 of file RelationsObject.h.

    {
      DataStore::Instance().findStoreEntry(this, m_cacheDataStoreEntry, m_cacheArrayIndex);
      if (!m_cacheDataStoreEntry)
        return nullptr;
      return m_cacheDataStoreEntry->getPtrAsArray();
    }

◆ getAssignmentState()

bool getAssignmentState ( ) const

Getter for status of assignment to a track.

Definition at line 185 of file SpacePoint.h.

185{ return m_isAssigned; }

Belle2::SpacePoint::m_isAssigned

bool m_isAssigned

Stores whether this SpacePoint is connected to a track.

Definition: SpacePoint.h:396

◆ getGenfitCompatible()

std::vector< genfit::PlanarMeasurement > getGenfitCompatible ( ) const

virtualinherited

returns a vector of genfit::PlanarMeasurement, which is needed for genfit::track.

This member ensures compatibility with genfit2. The return type is detector independent, but each entry will be of the same detector type, since a spacePoint can not contain clusters of different sensors and therefore of different detector types.

Definition at line 117 of file SpacePoint.cc.

{
  // XYRecoHit will be stored as their base-class, which is detector-independent.
  std::vector< genfit::PlanarMeasurement > collectedMeasurements;
 
 
  // get the related clusters to this spacePoint and create a genfit::PlanarMeasurement for each of them:
  if (getType() == VXD::SensorInfoBase::SensorType::SVD) {
 
    auto relatedClusters = this->getRelationsTo<SVDCluster>("ALL");
    for (unsigned i = 0; i < relatedClusters.size(); i++) {
      collectedMeasurements.push_back(SVDRecoHit(relatedClusters[i]));
    }
 
  } else if (getType() == VXD::SensorInfoBase::SensorType::PXD) {
 
    // since we do not know the name of the attached PXDCluster, getRelatedTo does not work, however, getRelationsTo seems to be less sensible and therefore can be used, but in this case, one has to loop over the entries (which should be only one in this case)
    auto relatedClusters = this->getRelationsTo<PXDCluster>("ALL");
    for (unsigned i = 0; i < relatedClusters.size(); i++) {
      collectedMeasurements.push_back(PXDRecoHit(relatedClusters[i]));
    }
 
  } else {
    B2FATAL("unknown detector type");
  }
 
  B2DEBUG(20, "SpacePoint::getGenfitCompatible(): collected " << collectedMeasurements.size() << " meaturements");
 
  return collectedMeasurements;
}

◆ getGlobalCoordinates()

B2Vector3D getGlobalCoordinates	(	const std::pair< double, double > &	hitLocal,
		VxdID	vxdID,
		const VXD::SensorInfoBase *	aSensorInfo = `nullptr`
	)

staticinherited

converts a local hit on a given sensor into global coordinates.

so this practically does what sensorInfo::pointToGlobal is doing, the difference is, that you do not need to have the sensorInfo beforehand (it will be retrieved using the VxdID) first parameter is the local hit (as provided by getU and getV!) stored as a pair of doubles. second parameter is the coded vxdID, which carries the sensorID. third parameter, a sensorInfo can be passed for testing purposes. If no sensorInfo is passed, the member gets its own pointer to it.

ATTENTION: this function assumes, that for wedged sensors, the uCoordinate is already adapted to the vCoordinate!

Definition at line 204 of file SpacePoint.cc.

{
  //We need some handle to translate IDs to local and global coordinates.
  if (aSensorInfo == nullptr) {
    aSensorInfo = &VXD::GeoCache::getInstance().getSensorInfo(vxdID);
  }
 
  // the second parameter set to true results in alignment constants being applied
  return aSensorInfo->pointToGlobal(ROOT::Math::XYZVector(hitLocal.first, hitLocal.second, 0), true);
}

◆ getIfClustersAssigned()

std::pair< bool, bool > getIfClustersAssigned ( ) const

inlineinherited

Returns, if u(v)-coordinate is based on cluster information.

.first is true, if u-cluster information is present
.second is true, if v-cluster information is present.

Definition at line 162 of file SpacePoint.h.

162{ return m_clustersAssigned; }

Belle2::SpacePoint::m_clustersAssigned

std::pair< bool, bool > m_clustersAssigned

The bool value is true, when correct information of the coordinate exists.

Definition: SpacePoint.h:365

◆ getInfo()

std::string getInfo ( ) const

inlineinherited

Return a short summary of this object's contents in raw text format.

Returns the contents of getInfoHTML() while translating line-breaks etc.

Note: : You don't need to implement this function (it's not virtual), getInfoHTML() is enough.

Definition at line 370 of file RelationsObject.h.

    {
      return _RelationsInterfaceImpl::htmlToPlainText(getInfoHTML());
    }

◆ getInfoHTML()

virtual std::string getInfoHTML ( ) const

inlinevirtualinherited

Return a short summary of this object's contents in HTML format.

Reimplement this in your own class to provide useful output for display or debugging purposes. For example, you might do something like:

std::stringstream out;
out << "<b>PDG</b>: " << m_pdg << "<br>";
out << "<b>Covariance Matrix</b>: " << HTML::getString(getCovariance5()) << "<br>";
return out.str();

See also: Particle::getInfoHTML() for a more complex example.; HTML for some utility functions.; Use getInfo() to get a raw text version of this output.

        return 2;
      }
      return 1;
    }
