 <p>Each <a class="el" href="classabigail_1_1comparison_1_1diff.html">diff</a> node has a property named <em>Canonical Diff Node</em>. If <code>D</code> is a diff node, the canonical diff node of <code>D</code>, noted <code>C(D)</code> is a particular diff node that is equal to <code>D</code>. Thus, a fast way to compare two <a class="el" href="classabigail_1_1comparison_1_1diff.html">diff</a> node is to perform a pointer comparison of their canonical diff nodes.</p>
 <p>A set of equivalent <a class="el" href="classabigail_1_1comparison_1_1diff.html">diff</a> nodes is a set of diff nodes that all have the same canonical node. All the nodes of that set are equal.</p>
 <p>A canonical node is registereded for a given diff node by invoking the method <a class="el" href="classabigail_1_1comparison_1_1diff__context.html#a2508fdea9043690d04e3cba05646537d" title="Set the canonical diff node property of a given diff node appropriately.">diff_context::initialize_canonical_diff()</a>.</p>
