◆ DerivedType
|
inherited |
The type of derived iterator.
The iterator has to define following functions have to be present:
// Access the value referred to.
// Access the value at some other location
Reference elementAt(n) const;
// Compare for equality with j
bool equals(j);
// position the iterator at the next element.
void increment()
// position the iterator at the previous element.
void decrement()
// advance the iterator by a number of positions-
void advance(DifferenceType n);
// calculate the distance to another iterator.
// One should incorporate an assertion whether
// the same containers are referenced
DifferenceType distanceTo(j) const;
std::ptrdiff_t DifferenceType
The type of the difference between two positions.
