forEach

public final <H extends RowHandler<? super T>> H forEach(ResultSet rs,
                                                         H handler)

                                                         MappingException

Description copied from interface: JdbcMapper

Loop over the resultSet, map each row to a new instance of T and call back the handler

The method will return the handler passed as an argument so you can easily chain the calls like
List<T> list = mapper.forEach(rs, new ListHandler<T>()).getList();

Type Parameters:

H - the row handler type

Parameters:

rs - the resultSet

handler - the handler that will get the callback

Returns:

the handler passed in

Throws:

SQLException - if sql error occurs

MappingException - if an error occurs during the mapping

newForEachIterator

protected abstract ForEachIterator<T> newForEachIterator(ResultSet rs)
                                                  throws SQLException

Throws:

SQLException

iterate

@Deprecated
public final Iterator<T> iterate(ResultSet rs)
                                      throws SQLException,
                                             MappingException

Deprecated.

Throws:

SQLException

MappingException

iterator

public final Iterator<T> iterator(ResultSet rs)
                           throws SQLException,
                                  MappingException

Parameters:

rs - the result set

Returns:

an iterator that will return a map object for each row of the result set.

Throws:

SQLException - if sql error occurs

MappingException - if an error occurs during the mapping

stream

public final Stream<T> stream(ResultSet rs)
                       throws SQLException,
                              MappingException

Parameters:

rs - the result set

Returns:

a stream that will contain a map object for each row of the result set.

Throws:

SQLException - if sql error occurs

MappingException - if an error occurs during the mapping
