T - Type that the mapRow returns.

public interface RawRowMapper<T>

Parameterized row mapper that takes output from the GenericRawResults and returns a T. Is used in the Dao.queryRaw(String, RawRowMapper, String...) method.

Method Detail

mapRow

T mapRow(String[] columnNames,
         String[] resultColumns)
  throws SQLException

Used to convert a raw results row to an object.

NOTE: If you are using the StatementBuilder.prepareStatementString() to build your query, it may have added the id column to the selected column list if the Dao object has an id you did not include it in the columns you selected. So the results might have one more column than you are expecting.

Parameters:

columnNames - Array of names of columns.

resultColumns - Array of result columns.

Returns:

The created object with all of the fields set from the results. Return null if there is no object generated from these results.

Throws:

SQLException - If there is any critical error with the data and you want to stop the paging.
