<p><b>First, a warning about names:</b> although this class is named <a class="el" href="classKatabatic_1_1Observer.html" title="Observer Design Pattern, Observer part. ">Observer</a>, it is intended to be an attribute nested inside the whole object which is indeed, the true <a class="el" href="classKatabatic_1_1Observer.html" title="Observer Design Pattern, Observer part. ">Observer</a>. This nesting object is called, most of the time the <b>owner</b> in the following. But sometimes, for simplification it may also be called the <a class="el" href="classKatabatic_1_1Observer.html" title="Observer Design Pattern, Observer part. ">Observer</a>.</p>

<p>To retrieve the <em>owner</em> from the <a class="el" href="classKatabatic_1_1Observer.html" title="Observer Design Pattern, Observer part. ">Observer</a> attribute, we uses the offset from the attribute in the <em>owner</em>. This offset is computed once and for all the first time the template constructor is called. </p>
