Constructor Detail


public UpdatableSqlQuery.ResultReaderImpl(int rowsExpected,
                                          Map context)
Use an array results. More efficient if we know how many results to expect.

Method Detail


public void processRow(ResultSet rs)
                throws SQLException
Description copied from interface: RowCallbackHandler
Implementations must implement this method to process each row of data in the ResultSet. This method should not call next() on the ResultSet; it is only supposed to extract values of the current row.

Exactly what the implementation chooses to do is up to it: A trivial implementation might simply count rows, while another implementation might build an XML document.

Specified by:
processRow in interface RowCallbackHandler
rs - the ResultSet to process (pre-initialized for the current row)
SQLException - if a SQLException is encountered getting column values (that is, there's no need to catch SQLException)


public List getResults()
Description copied from interface: ResultReader
Return all results, disconnected from the JDBC ResultSet. Never returns null; returns the empty collection if there were no results.

Specified by:
getResults in interface ResultReader
