Why is there no difference between <code >iterator_of<C>::type</code> and <code >const_iterator_of<C>::type</code>
|
||
|
|
for <code >std::pair<iterator, iterator></code>.
|
||
|
|
</li>
|
||
|
|
<p >
|
||
|
|
In general it is not possible nor desirable to find a corresponding <code >const_iterator</code>.
|
||
|
|
When it is possible to come up with one, the client might choose to construct a <code >std::pair<const_iterator,const_iterator></code>
|
||
|
|
object.

Why is there not supplied more types or more functions?
|
||
|
|
<p >
|
||
|
|
The library have been kept small because its current interface will serve
|
||
|
|
most purposes. If and when a genuine need arises for more functionality, it can
|
||
|
|
be implemented.

How should I implement generic algorithms for ranges?
|
||
|
|
<p >
|
||
|
|
One should always start with a generic algorithm that takes two
|
||
|
|
iterators (or more) as
|
||
|
|
input. Then use Boost.Range to build handier versions on top of the
|
||
|
|
iterator based algorithm. Please notice that once the range version
|
||
|
|
of the algorithm is done, it makes sense <i>not</i> to expose the
|
||
|
|
iterator version in the public interface.
