V::rel_type rel ()
 Provides read access to relations - the object types and their connectivity are defined by the class V which has to be a subtype of either LC1To1Relation, LC1ToNRelation or LCNToNRelation.

Member Function Documentation

virtual const FloatVec& EVENT::Vertex::getCovMatrix ( ) const
pure virtual

Covariance matrix of the position (stored as lower triangle matrix, i.e.

cov(xx),cov(y,x),cov(y,y) ).

Implemented in IMPL::VertexImpl.

Referenced by SIO::SIOVertexHandler::write().

virtual bool EVENT::Vertex::isPrimary ( ) const
pure virtual

Checks if the Vertex is the primary vertex of the event.

Only one primary vertex per event is allowed

Implemented in IMPL::VertexImpl.
