Forward SequenceA Forward Sequence is a Sequence which guarantees that its elements are arranged in a definite order, and that the ordering will not change spontaneously [1]. Iterators into a forward sequence satisfy the Forward Iterator requirements.
Forward Sequence does not define any new expressions beyond those defined in Sequence. However, it refines the expression requirements.
| Expression | Expression type |
|---|---|
typename begin<s>::type | A model of Forward Iterator |
typename end<s>::type | A model of Forward Iterator |
For any forward sequence s the following invariants always hold:
s will access its elements in the same order.
[1] Both between compilation sessions and from iteration to iteration.
