LoadAll()?

I am new to Qcodo and PHP.  I am trying to find documentation on the LoadAll() function.  Can anyone point me in the right direction?

I have a mySql table called Country with the following fields.
   country_id int(10)            
     short_description varchar(50)                
     abbreviation char(2)              
     state_flag bit(1)                
     province_flag bit(1)

The country class has the following LoadAll method

/**        
* Load all Companies
* @param QQClause[] $objOptionalClauses additional optional QQClause objects for this query
* @return Company[]
*/
public static function LoadAll($objOptionalClauses = null) {
// Call Company::QueryArray to perform the LoadAll query
    try {
   return Company::QueryArray(QQ::All(), $objOptionalClauses);
   } catch (QCallerException $objExc) {
   $objExc->IncrementOffset();
   throw $objExc;
   }
    }

I would like to be able to sort the countries by the short_description field.  But I don't understand the syntax and variables enough to do that yet.
