Method Details

map

public T map(ResultSet rs,
 StatementContext ctx)
      throws SQLException

Description copied from interface: RowMapper

Map the current row of the result set. This method should not cause the result set to advance; allow Jdbi to do that, please.

Specified by:

map in interface RowMapper<T>

Parameters:

rs - the result set being iterated

ctx - the statement context

Returns:

the value to produce for this row

Throws:

SQLException - if anything goes wrong go ahead and let this percolate; Jdbi will handle it

specialize

public RowMapper<T> specialize(ResultSet rs,
 StatementContext ctx)
                        throws SQLException

Description copied from interface: RowMapper

Returns a specialized row mapper, optimized for the given result set.

Before mapping the result set from a SQL statement; Jdbi will first call this method to obtain a specialized instance. The returned mapper will then be used to map the result set rows, and discarded.

Implementing this method is optional; the default implementation returns this. Implementors might choose to override this method to improve performance, e.g. by matching up column names to properties once for the entire result set, rather than repeating the process for every row.

Specified by:

specialize in interface RowMapper<T>

Parameters:

rs - the result set to specialize over

ctx - the statement context to specialize over

Returns:

a row mapper equivalent to this one, possibly specialized.

Throws:

SQLException - if anything goes wrong go ahead and let this percolate; Jdbi will handle it
