Detailed Description

template<class AccumType, class DataIterator, class MaskIterator = const Bool *, class WeightsIterator = DataIterator>
struct casacore::StatisticsDataset< AccumType, DataIterator, MaskIterator, WeightsIterator >::ChunkData

holds information about a data chunk.

A data chunk is either an individual underlying dataset (if no data provider), or a chunk of data served by the data provider if it exists.

PtrHolder<std::pair<MaskIterator, uInt> > casacore::StatisticsDataset< AccumType, DataIterator, MaskIterator, WeightsIterator >::ChunkData::mask

associated mask.

If nullptr, then there is no mask. If there is a mask, the second member is the mask stride.

PtrHolder<std::pair<DataRanges, Bool> > casacore::StatisticsDataset< AccumType, DataIterator, MaskIterator, WeightsIterator >::ChunkData::ranges

associated ranges.

If nullptr, then there are none. If not, the second member of the pair indicates if they are include ranges.

associated weights.

If nullptr, then there are no weights.
