Description copied from interface: CsvMapper

Will map each row of the content of reader to an object of type T and will pass that object to the handle via the CheckedConsumer.handler(T t) call back.

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

Specified by:

forEach in interface CsvMapper<T>

Type Parameters:

H - the row handler type

Parameters:

reader - the reader

handle - the callback newInstance

Returns:

the callback newInstance

Throws:

IOException - if an io error occurs

org.simpleflatmapper.map.MappingException - if an mapping error occurs

forEach

public <H extends org.simpleflatmapper.util.CheckedConsumer<? super T>> H forEach(org.simpleflatmapper.lightningcsv.CsvReader reader,
