Member Function Documentation

virtual void genie::geometry::GeomVolSelectorI::BeginPSList ( const PathSegmentList * untrimmed ) const

pure virtual

Every derived version must also respond to a signal that starts a new path segment list processing and ends it. In general they can simply ignore the signal. If the derived class needs to cache something, make it mutable

Implemented in genie::geometry::GeomVolSelectorBasic, genie::geometry::GeomVolSelectorFiducial, and genie::geometry::GeomVolSelectorRockBox.

Referenced by GenerateTrimmedList().

virtual void genie::geometry::GeomVolSelectorI::EndPSList ( ) const

pure virtual

Implemented in genie::geometry::GeomVolSelectorBasic, genie::geometry::GeomVolSelectorFiducial, and genie::geometry::GeomVolSelectorRockBox.

Referenced by GenerateTrimmedList().

PathSegmentList * GeomVolSelectorI::GenerateTrimmedList ( const PathSegmentList * untrimmed ) const

virtual

create and return a new PathSegmentList from the old list relinquishes ownership of returned object
