MCLFPostFilter Class Reference

class MCLFPostFilter

Post filter interface for Content Listing Framework. With this interface client you can add own post filter to exclude items from list model. Example:

  // This example filters items by drive letter:
  // Items that are in phone memory are included to the list model.
  // All other items will be filtered.
  void CMyFilter::FilterItemsL( const TArray<MCLFItem*>& aItemList,
                                RPointerArray<MCLFItem>& aFilteredItemList )
      {
      TCharF phoneMemory( PathInfo::PhoneMemoryRootPath()[0] );
      TInt count( aItemList.Count() );
      for( TInt i = 0 ; i < count ; ++i )
          {
          TPtrC ptr;
          MCLFItem* item = aItemList[i];
          TInt error( item->GetField( ECLFFieldIdDrive, ptr ) );
          if( error == KErrNone )
              {
              TCharF memory( ptr[0] );
              if( memory == phoneMemory )
                  {
                  aFilteredItemList.AppendL( item );
                  }
              }
          }
      }
