Constructors
RowIterator
RowIterator(
const RowIterator & other
);
Creates a copy of other RowIterator.
RowIterator
RowIterator(
RowIterator && other
) noexcept;
Move constructor.
RowIterator
RowIterator(
RecordSet * pRecordSet,
bool positionEnd
);
Creates the RowIterator and positions it at the end of the recordset if positionEnd is true. Otherwise, it is positioned at the beginning.
Destructor
~RowIterator
~RowIterator();
Destroys the RowIterator.
Member Functions
operator != 
bool operator != (
const RowIterator & other
) const;
Inequality operator.
operator *
Row & operator * () const;
Returns reference to the current row.
operator +
RowIterator operator + (
std::size_t diff
) const;
Returns a copy the RowIterator advanced by diff positions.
operator ++
const RowIterator & operator ++ () const;
Advances by one position and returns current position.
operator ++
RowIterator operator ++ (
int
) const;
Advances by one position and returns copy of the iterator with previous current position.
operator -
RowIterator operator - (
std::size_t diff
) const;
Returns a copy the RowIterator backed by diff positions. Throws RangeException if diff is larger than current position.
operator --
const RowIterator & operator -- () const;
Goes back by one position and returns copy of the iterator with previous current position.
operator --
RowIterator operator -- (
int
) const;
Goes back by one position and returns previous current position.
operator =
RowIterator & operator = (
const RowIterator & other
);
Assigns the other RowIterator.
operator =
RowIterator & operator = (
RowIterator && other
) noexcept;
Move assignment.
operator ==
bool operator == (
const RowIterator & other
) const;
Equality operator.
operator->
Row * operator-> () const;
Returns pointer to the current row.
swap
void swap(
RowIterator & other
) noexcept;
Swaps the RowIterator with another one.
Variables
POSITION_END 
static const std::size_t POSITION_END;
End position indicator.
