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