Method Detail

of

static <R> RowMapper<R> of(ThrowingFunction<ResultSet,R,SQLException> mapper)

of

static <R> RowMapper<R> of(RowMapper<R> mapper)

fromResultSet

R fromResultSet(ResultSet resultSet,
                int rowNum)
         throws SQLException

Throws:

SQLException

fromResultSet

default R fromResultSet(ResultSet resultSet)
                 throws SQLException

Obtain the result from the current row of a ResultSet.

Parameters:

resultSet - the ResultSet

Returns:

the result

Throws:

SQLException - if an error happen when retrieving data from the ResultSet.

andThen

default <S> RowMapper<S> andThen(Function<? super R,S> resultMapper)

Create a new mapper which takes the result of this mapper and applies the given Function to yield another result.

Type Parameters:

S - the output type of the given resultMapper function, which also become the type of the result produced by the new row mapper.

Parameters:

resultMapper - the function to apply to the result

Returns:

the new row mapper

combinedWith

default <S> RowMapper.Tupled<R,S> combinedWith(RowMapper<S> otherMapper)

Create a new row mapper which first runs this mapper and then the given mapper, and combines the two results into a tuple-type container.

Parameters:

otherMapper - the mapper to run in addition to this.

Returns:

the new mapper
