Interface Grid.DataSource

Enclosing class:

Grid

public static interface Grid.DataSource

Interface that can be used to fetch data on demmand. This makes the grid slower but uses much less memory. Here's a sample:

   public String[][] getItems(int startIndex, int count)
   {
      if (activeRS != null)
      {
         activeRS.absolute(startIndex);
         return activeRS.getStrings(count);
      }
      return null;
   }
 

See the AddressBook sample on Litebase.
