Typedef Documentation

PeriodsDivisionMapT

typedef ddcMapFile<DWORD, DWORD> PeriodsDivisionMapT

a type for mappping an index item no to its period division

PeriodsDivisionMapR

typedef PeriodsDivisionMapT::MapT PeriodsDivisionMapR

low-level resident std::map<> implementation in PeriodsDivisionMap::m_map

PeriodsDivisionMapV

typedef PeriodsDivisionMapT::RecFileT PeriodsDivisionMapV

low-level virtual mmap()-based implementation in PeriodsDivisionMap::m_rfile

CSuffixIndex

typedef ddcVecFile<DWORD> CSuffixIndex

CSuffixIndex is a vector of Item-IDs sorted in ascending order by reverse string-value, for fast binary search of string-suffixes.
