Detailed Description

Class SimHitBase - A common base for subdetector SimHits.

This is a base class from which other SimHit classes have to be derived in to be usable for background mixing. It implements a background type tag and a method to shift the SimHit in time.

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).

160 }

◆ 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.

174 auto fromRels = sourceObj->getRelationsFrom<RelationsInterface<BASE>>("ALL");
175 for (unsigned int iRel = 0; iRel < fromRels.size(); iRel++) {
176 fromRels.object(iRel)->addRelationTo(this, fromRels.weight(iRel));
177 }
178
179 auto toRels = sourceObj->getRelationsTo<RelationsInterface<BASE>>("ALL");
180 for (unsigned int iRel = 0; iRel < toRels.size(); iRel++) {
181 this->addRelationTo(toRels.object(iRel), toRels.weight(iRel));
