Detailed Description

template<typename T, typename ChunkingPolicy = Chunked>
class o2::soa::ColumnIterator< T, ChunkingPolicy >

Iterator on a single column. FIXME: the ChunkingPolicy for now is fixed to Flat and is a mere boolean which is used to switch off slow "chunking aware" parts. This is ok for now, but most likely we should move the whole chunk navigation logic there.

Constructor & Destructor Documentation

◆ ColumnIterator() [1/4]

template<typename T , typename ChunkingPolicy = Chunked>
o2::soa::ColumnIterator< T, ChunkingPolicy >::ColumnIterator ( arrow::ChunkedArray const *  column)
inline

Constructor of the column iterator. Notice how it takes a pointer to the ChunkedArray (for the data store) and to the index inside it. This means that a ColumnIterator is actually only available as part of a RowView.
