Hi,<br><br>the following methods:<br><ul><li>Collection&gt;&gt;topologicallySortedUsing:</li><li>SortedCollection&gt;&gt;sortTopologically:</li><li>SortedCollection&gt;&gt;should:precede:</li></ul>are in the dirty methods list. The only sender of this is a test case for topologically sorted.<br>
<br>Anyway, I don&#39;t understand the need for such behavior in SortedCollection... the topological sort is used in graph theory to obtain a total order of the nodes in a directed acyclic graph.. From my point of view SortedCollection should not implement this behavior... the sortTopologically: uses the same sort block used for standard sorting in SortedCollection, from the implementation I think that additionally it retains the original partial order of the equal elements (some kind of stable sorting, however this is not the intention for the method name).<br>
<br>Summarizing.. I vote for removal of this behavior...<br><br>Anyone knowns if there&#39;s another meaning for topological sorting?<br><br>Waiting for comments<br><br>Gabriel<br><br>
