<h2 class="description">Description</h2>
<div class="nodescription">no description available, TGenericStructList description follows</div><p>
Generic list of types that are compared by CompareByte.
<p>This is equivalent to TFPGList, except it doesn't override <a class="normal" href="CastleGenericLists.TGenericStructList.html#IndexOf">IndexOf</a>, so your type doesn't need to have a "=" operator built-in inside FPC. When calling <a class="normal" href="CastleGenericLists.TGenericStructList.html#IndexOf">IndexOf</a> or Remove, it will simply compare values using CompareByte, this is what TFPSList.IndexOf uses. This way it works to create lists of records, vectors (constant size arrays), old-style TP objects, and also is suitable to create a list of methods (since for methods, the "=" is broken, for Delphi compatibility, see <a href="http://bugs.freepascal.org/view.php?id=9228">http://bugs.freepascal.org/view.php?id=9228</a>).
<p>We also add some trivial helper methods like <a class="normal" href="CastleGenericLists.TGenericStructList.html#Add">Add</a> and <a class="normal" href="CastleGenericLists.TGenericStructList.html#L">L</a>.</p>
