	)		const

inlineinherited

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

Parameters

object	The object to which the relation should point.
weight	The weight of the relation.
namedRelation	Additional name for the relation, or "" for the default naming

Definition at line 144 of file RelationsObject.h.

◆ addRelationTo() [2/2]

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

Parameters

object	The object to which the relation should point.
weight	The weight of the relation.
namedRelation	Additional name for the relation, or "" for the default naming

Definition at line 157 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 172 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 372 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();

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