GetNextGridEntry()

bool cbm::algo::ca::GridArea::GetNextGridEntry ( ca::HitIndex_t & ind )

inline

look up the next grid entry in the requested area

Returns

ind - the entry index in the grid.GetEntries() vector

true if the entry is found, false if there are no more entries in the area

bool cbm::algo::ca::GridArea::GetNextObjectId ( ca::HitIndex_t & objectId )

inline

look up the next object id in the requested area

Returns

objectId - the id of the object

true if the object is found, false if there are no more pbjects in the area
