<a name="details" id="details"></a><h2 class="groupheader">Detailed Description</h2>
<div class="textblock"><p>Utility class that makes any derived class non-copyable. </p>
<p>This class makes its instances non-copyable, by explicitly disabling its copy constructor and its assignment operator.</p>
<p>To create a non-copyable class, simply inherit from <a class="el" href="classsf_1_1NonCopyable.html" title="Utility class that makes any derived class non-copyable. ">sf::NonCopyable</a>.</p>
<p>The type of inheritance (public or private) doesn't matter, the copy constructor and assignment operator are declared private in <a class="el" href="classsf_1_1NonCopyable.html" title="Utility class that makes any derived class non-copyable. ">sf::NonCopyable</a> so they will end up being inaccessible in both cases. Thus you can use a shorter syntax for inheriting from it (see below).</p>
<p>Usage example: </p><div class="fragment"><div class="line"><span class="keyword">class </span>MyNonCopyableClass : <a class="code" href="classsf_1_1NonCopyable.html">sf::NonCopyable</a></div><div class="line">{</div><div class="line"> ...</div><div class="line">};</div></div><!-- fragment --><p>Deciding whether the instances of a class can be copied or not is a very important design choice. You are strongly encouraged to think about it before writing a class, and to use <a class="el" href="classsf_1_1NonCopyable.html" title="Utility class that makes any derived class non-copyable. ">sf::NonCopyable</a> when necessary to prevent many potential future errors when using it. This is also a very important indication to users of your class. </p>

<p>Default destructor. </p>
<p>By declaring a protected destructor it's impossible to call delete on a pointer of <a class="el" href="classsf_1_1NonCopyable.html" title="Utility class that makes any derived class non-copyable. ">sf::NonCopyable</a>, thus preventing possible resource leaks. </p>
