[heading Preconditions]
|

|

Let `it`[sub `i`] be the iterator obtained by incrementing (or decrementing if `n` is negative) `it` by `i`. All the iterators `it`[sub `i`] for `i` = 0, 1, 2, ..., `|n|` should be valid.

If `Iterator` does not model [link iterator.concepts.concepts_traversal.bidirectional Bidirectional Traversal Iterator], `n` should be non-negative.

||||
|
||||
[heading Complexity]

|

If `Iterator` models [link iterator.concepts.concepts_traversal.random_access Random Access Traversal Iterator], it takes constant time; otherwise it takes linear time.

[section:next_prior Function templates `next()` and `prior()`]
|
||||
|
||||
Certain data types, such as the C++ Standard Library's forward and bidirectional iterators, do not provide addition and subtraction via `operator+()` or `operator-()`. This means that non-modifying computation of the next or prior value requires a temporary, even though `operator++()` or `operator--()` is provided. It also means that writing code like `itr+1` inside a template restricts the iterator category to random access iterators.

||||
The `next()` and `prior()` functions provide a simple way around these problems:

First, `boost::next()` and `boost::prior()` are compatible not only with iterators but with any type that provides arithmetic operators `operator++()`, `operator--()`, `operator+()`, `operator-()`, `operator+=()` or `operator-=()`. For example, this is possible:

For some kinds of iterators, such as [link iterator.specialized.transform transform iterators], the standard iterator category does not reflect the traversal category correctly and therefore `std::next()` and `std::prev()` will fall back to linear complexity.

[section:utilities_testing Testing and Concept Checking]
|
||||
|
||||
The iterator concept checking classes provide a mechanism for a
|
||||
template to report better error messages when a user instantiates
|
||||
the template with a type that does not meet the requirements of the
|
||||
template.
|
||||
|
||||
For an introduction to using concept checking classes, see
|
||||
the documentation for the
|
||||
[@../../concept_check/index.html `boost::concept_check`] library.
