+/**
+*  Sorting style for Content Listing Framework.
+*  This class can be used to define primary and secondary sorting styles for
+*  Content Listing Framework list model. Sorting styles are used to sort the
+*  list model.<br><br>
+*  Secondary sorting style is used to sort items that could not be sorted by
+*  the primary sorting style. In other words, items that do not have the
+*  field defined by primary or any previous secondary sorting style, the items
+*  are sorted using the next secondary sorting style. When a secondary sorting
+*  style is appended, it becomes the least significant sorting style until a
+*  new one is added after it. Items with undefined fields are placed before or
+*  after items with defined fields, depending on the undefined field position
+*  setting in MCLFSortingStyle.
+*  <br><br>
+*  Usage:
+*  @code
+*  // Create a sorting style instance
+*  MCLFSortingStyle* sortingStyle = ContentListingFactory::NewSortingStyleLC();
+*
+*  // Set sort ordering
+*  sortingStyle->SetOrdering( ECLFOrderingDescending );
+*
+*  // Set undefied item position. Undefined items are items that doesn't
+*  // have field that is defined in sorting style fields
+*  sortingStyle->SetUndefinedItemPosition( ECLFSortingStyleUndefinedEnd );
+*
+*  // All sorting style parameter fields are string type
+*  sortingStyle->SetSortingDataType( ECLFItemDataTypeDesC );
+*
+*  // Set default sorting parameter
+*  sortingStyle->AddFieldL( ECLFFieldIdSongName );
+*
+*  // Set secondary sorting parameter
+*  sortingStyle->AddFieldL( ECLFFieldIdFileName );
+*
+*  // If item doesn't have ECLFFieldIdSongName field then
+*  // ECLFFieldIdFileName field is used to sort item.
