CalculateDistribution()

template<typename Object>

bool osmscout::AreaIndexGenerator< Object >::CalculateDistribution ( const TypeConfig & typeConfig, const ImportParameter & parameter, Progress & progress, const std::vector< TypeInfoRef > & types, std::vector< TypeData > & typeData, const MagnificationLevel & minLevelParam, const MagnificationLevel & maxLevelParam, bool useMmap, MagnificationLevel & maxLevel ) const

CalculateStatistics()

template<typename Object>

void osmscout::AreaIndexGenerator< Object >::CalculateStatistics ( const MagnificationLevel & level, TypeData & typeData, const CoordCountMap & cellFillCount ) const

protected

Calculate internal statistics that are the base for deciding if the given object type is indexed at the given index level.

Parameters

level
typeData
cellFillCount

FitsIndexCriteria()

template<typename Object>

bool osmscout::AreaIndexGenerator< Object >::FitsIndexCriteria ( Progress & progress, const TypeInfo & typeInfo, const CoordCountMap & cellFillCount ) const

MakeAreaIndex()

template<typename Object>

bool osmscout::AreaIndexGenerator< Object >::MakeAreaIndex ( const TypeConfigRef & typeConfig, const ImportParameter & parameter, Progress & progress, const std::vector< TypeInfoRef > & types, const MagnificationLevel & areaIndexMinMag, const MagnificationLevel & areaIndexMaxMag, bool useMmap )

WriteBitmap()

template<typename Object>

void osmscout::AreaIndexGenerator< Object >::WriteBitmap ( Progress & progress, FileWriter & writer, const TypeInfo & typeInfo, const TypeData & typeData, const CoordOffsetsMap & typeCellOffsets )

protected

For each cell we store a file offset to the bitmap data or 0, if there is no data for the cell. The bitmap entry itself contains the number of offsets followed by the offsets themselves (delta-encoded).

Parameters

progress
writer
typeInfo
typeData
typeCellOffsets

WriteTypeId()

template<typename Object>

virtual void osmscout::AreaIndexGenerator< Object >::WriteTypeId ( const TypeConfigRef & typeConfig, const TypeInfoRef & type, FileWriter & writer ) const
