Constructor Detail

UpdatableSqlQuery.ResultReaderImpl

public UpdatableSqlQuery.ResultReaderImpl(int rowsExpected,
                                          Map context)

Use an array results. More efficient if we know how many results to expect.

Method Detail

processRow

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, but extract the current values. 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

Parameters:

rs - the ResultSet to process

Throws:

SQLException - if a SQLException is encountered getting column values (that is, there's no need to catch SQLException)

getResults

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
