RelationsInterface< TObject > RelationsObject
Provides interface for getting/adding relations to objects in StoreArrays.

Member Function Documentation

◆ addRelationTo() [1/2]

void addRelationTo ( const RelationsInterface< BASE > *  object,
float  weight = 1.0,
const std::string &  namedRelation = "" 
) const
inlineinherited

Add a relation from this object to another object (with caching).

Parameters
objectThe object to which the relation should point.
weightThe weight of the relation.
namedRelationAdditional name for the relation, or "" for the default naming

Definition at line 142 of file RelationsObject.h.

◆ addRelationTo() [2/2]

void addRelationTo ( const TObject *  object,
float  weight = 1.0,
const std::string &  namedRelation = "" 
) const
inlineinherited

Add a relation from this object to another object (no caching, can be quite slow).

Parameters
objectThe object to which the relation should point.
weightThe weight of the relation.
namedRelationAdditional name for the relation, or "" for the default naming

Definition at line 155 of file RelationsObject.h.

◆ 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.

◆ 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.

◆ 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();
std::string getString(const TMatrixFBase &matrix, int precision=2, bool color=true)
get HTML table representing a matrix.
Definition: HTML.cc:24
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.

Reimplemented in RecoTrack, TRGSummary, TrackFitResult, Track, SoftwareTriggerResult, PIDLikelihood, MCParticle, Cluster, and Particle.

Definition at line 362 of file RelationsObject.h.

◆ getName()

virtual std::string getName ( ) const
inlinevirtualinherited

Return a short name that describes this object, e.g.

pi+ for an MCParticle.

Reimplemented in SpacePoint, MCParticle, and Particle.

Definition at line 344 of file RelationsObject.h.
