A huge effort has been made to port the library to as many compilers as possible.

Full support for built-in arrays require that the compiler supports class
|
2004-08-24 15:58:01 +00:00
|
|
|
template partial specialization. For non-conforming compilers there might be a
|
|
|
|
|
chance that it works anyway thanks to workarounds in the type traits library.
|
|
|
|

Notice also that some compilers cannot do function template ordering properly.
|
|
|
|
|
In that case one must rely of <a
|
|
|
|
|
href="boost_range.html#range_result_iterator"><code >range_result_iterator</code></a>
|
|
|
|
|
and a single function definition instead of overloaded versions for const and
|
|
|
|
|
non-const arguments.
|
|
|
|
|
|
|
|
|
|
So if one cares about old compilers, one should not pass rvalues to the
|
|
|
|
|
functions.

For maximum portability you should follow these guidelines:
|
|
|
|
|
|
|
|
|
|
<ol>
|
|
|
|
|
<li>
|
2004-09-16 19:07:04 +00:00
|
|
|
do not use built-in arrays,
|
2004-08-24 15:58:01 +00:00
|
|
|
<li>
|
|
|
|
|
do not pass rvalues to <a
|
|
|
|
|
href="boost_range.html#begin"><code>begin()</code></a>, <a
|
|
|
|
|
href="boost_range.html#end"><code>end()</code></a> and <a href="utility_class.html#iter_range">
|
|
|
|
|
<code>iterator_range</code></a> Range constructors and assignment operators,
|
|
|
|
|
<li>
|
2004-09-16 19:07:04 +00:00
|
|
|
use <a href="boost_range.html#const_begin"><code>const_begin()</code></a>
|
|
|
|
|
and <a href="boost_range.html#const_begin"><code>const_end()</code></a>
|
|
|
|
|
whenever your code by intention is read-only; this will also solve
|
|
|
|
|
most rvalue problems,
|
|
|
|
|
<li>
|
2004-08-24 15:58:01 +00:00
|
|
|
do not rely on ADL:
|
|
|
|
|
<ul>
|
|
|
|
|
<li>
|
|
|
|
|
if you overload functions, include that header <i>before</i> the headers in this
|
|
|
|
|
library,
|
|
|
|
|
<li>
|
2004-09-16 19:07:04 +00:00
|
|
|
put all overloads in namespace <code>boost</code>.
|
2004-08-24 15:58:01 +00:00
|
|
|
</ul>
|
|
|
|
|
|
|
|
|
|
</ol>
