Use an array results.

Method Summary

List	getResults() Return all results, disconnected from the JDBC ResultSet.

Constructor Detail

MappingSqlQueryWithParameters.ResultReaderImpl

public MappingSqlQueryWithParameters.ResultReaderImpl(int rowsExpected,
                                                      Object[] parameters,
                                                      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; 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

Parameters:

rs - the ResultSet to process (pre-initialized for the current row)

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
