Class TupleStreamIterator<Tuple> (2.18.0)

A TupleStreamIterator<Tuple> is an "Input Iterator" that wraps a RowStreamIterator, parsing its elements into a sequence of StatusOr<Tuple> objects.

As an Input Iterator, the sequence may only be consumed once. See https://en.cppreference.com/w/cpp/named_req/InputIterator for more details.

Default constructing this object creates an instance that represents "end".

Each Row returned by the wrapped RowStreamIterator must be convertible to the specified Tuple template parameter.

Constructors

TupleStreamIterator(RowStreamIterator, RowStreamIterator)
