https://svn.boost.org/trac10/ticket/7842 <p> The "Introduction and Motivation" page for Range Adaptors has a number of issues: </p> <ol><li>The example where a use of boost::count_if is replaced by boost::count + the filtered adaptor is conceptually wrong (there is no reasonable value to pass as the second argument to boost::count to get the desired behaviour). In the example, a bogus argument called 'out' is passed. </li></ol><ol start="2"><li>More generally, the claim that "[in light of range adaptors] <strong><em>no</em></strong> algorithm with the _if suffix is needed" is misleading. See my analysis in this post for details: <a class="ext-link" href="http://boost.2283326.n4.nabble.com/range-count-vs-count-if-tp4374377p4388398.html"><span class="icon">​</span>http://boost.2283326.n4.nabble.com/range-count-vs-count-if-tp4374377p4388398.html</a> </li></ol><p> This section of the documentation needs to be cleaned up a bit, and it perhaps needs to make less bold claims :) </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/7842 Trac 1.4.3 Neil Groves Mon, 03 Mar 2014 18:58:57 GMT https://svn.boost.org/trac10/ticket/7842#comment:1 https://svn.boost.org/trac10/ticket/7842#comment:1 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">assigned</span> </li> </ul> <p> Corrected in the .qbk on the develop branch. </p> Ticket Neil Groves Tue, 04 Mar 2014 13:04:12 GMT https://svn.boost.org/trac10/ticket/7842#comment:2 https://svn.boost.org/trac10/ticket/7842#comment:2 <ul> <li><strong>milestone</strong> <span class="trac-field-old">To Be Determined</span> → <span class="trac-field-new">Boost 1.56.0</span> </li> </ul> Ticket Neil Groves Tue, 04 Mar 2014 13:56:26 GMT https://svn.boost.org/trac10/ticket/7842#comment:3 https://svn.boost.org/trac10/ticket/7842#comment:3 <ul> <li><strong>status</strong> <span class="trac-field-old">assigned</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">fixed</span> </li> </ul> <p> merged .qbk to master - html will be removed from git and put into build before 1.56 </p> Ticket
