public boolean absolute(int row)
                 throws PersistenceException
```
    use the jdbc 2.0 method to move to an absolute position in the resultset.
    
    Specified by:
    
    absolute in interface QueryResults
    
    Parameters:
    
    row - The row to move to
    
    Returns:
    
    ???
    
    Throws:
    
    PersistenceException - A persistence error occured
  - size
```
public int size()
         throws PersistenceException
```
    Uses the underlying db's cursors to most to the last row in the result set, get the row number via getRow(), then move back to where ever the user was positioned in the resultset.
    
    Specified by:
    
    size in interface QueryResults
    
    Returns:
    
    Size of the resulting result set.
    
    Throws:
    
    PersistenceException - A persistence error occured
  - hasMoreElements

public boolean hasMoreElements()
```
    Specified by:
    
    hasMoreElements in interface java.util.Enumeration<java.lang.Object>
  - hasMore
```
public boolean hasMore()
                throws PersistenceException
```
    Description copied from interface: QueryResults
    
    Returns true if there are any more results in the result set. If an error occured reading the last result, an exception will be thrown and the result set cannot be used further.
    
    Specified by:
    
    hasMore in interface QueryResults
    
    Returns:
    
    True if there are any more results in the result set
    
    Throws:
    
    PersistenceException - An error with the persistence engine

```
public java.lang.Object next()
                      throws PersistenceException,
                             java.util.NoSuchElementException
```
    Description copied from interface: QueryResults
    
    Returns the next result in the result set. If there are no more results (a previous cal to QueryResults.hasMore() returns false) this method will throw an exceptin. If an error occured reading the last result, an exception will be thrown and the result set cannot be used further.
    
    Specified by:
    
    next in interface QueryResults
