Detailed Description

Datastore class that holds position and momentum information of tracks that hit ARICH.

It can be created either form ExtHit (i.e. mdst Track extrapolated to ARICH aerogel plane) or ARICHAeroHit (i.e. MC hit of particle on ARICH aerogel plane). If selected, information of individual reconstruced photons associated with track (cherenkov angles) can be stored (see ARICHPhoton.h)

		float	weight = `1.0`,
		const std::string &	namedRelation = `""`
	)		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 142 of file RelationsObject.h.

◆ addRelationTo() [2/2]

		float	weight = `1.0`,
		const std::string &	namedRelation = `""`

◆ 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.

◆ getDirection()

Returns: track direction vector

Definition at line 139 of file ARICHTrack.h.

◆ getInfo()

inlineinherited

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

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();

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.
