Method Detail

map

public final T map(ROW row)
            throws MappingException

Description copied from interface: Mapper

map source object to a new newInstance of T

Specified by:

map in interface Mapper<ROW,SET>

Parameters:

row - object to map from

Returns:

a new mapped newInstance of T

Throws:

MappingException - if an exception occurs

map

public final T map(ROW row,
                   MappingContext<? super ROW> context)
            throws MappingException

Specified by:

map in interface Mapper<ROW,SET>

Throws:

MappingException

mapTo

public final void mapTo(ROW row,
                        T target,
                        MappingContext<? super ROW> context)
                 throws Exception

Description copied from interface: FieldMapper

map source object to target object.

Specified by:

mapTo in interface FieldMapper<ROW,SET>

Parameters:

row - object to map from

target - object to map to

context - the mapping context

Throws:

Exception - if an exception occurs

iterator

public final Iterator<T> iterator(SET rs)
                           throws E extends Exception,
                                  MappingException

Specified by:

iterator in interface EnumarableMapper<ROW,SET,T>

Parameters:

rs - the source

Returns:

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

Throws:

E - if source error occurs

MappingException - if an error occurs during the mapping

E extends Exception

stream

public final Stream<T> stream(SET set)
                       throws E extends Exception,
                              MappingException

Specified by:

stream in interface EnumarableMapper<ROW,SET,T>

Parameters:

set - the source

Returns:

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

Throws:

E - if source error occurs

MappingException - if an error occurs during the mapping

E extends Exception

forEach

public final <H extends org.simpleflatmapper.util.CheckedConsumer<? super T>> H forEach(SET set,
                                                                                        H handler)

Description copied from interface: EnumarableMapper

Loop over the resultSet, map each row to a new newInstance 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 = jdbcMapper.forEach(rs, new ListHandler<T>()).getList();

Specified by:

forEach in interface EnumarableMapper<ROW,SET,T>

Type Parameters:

H - the row handler type

Parameters:

set - the source

handler - the handler that will get the callback

Returns:

the handler passed in

Throws:

E - if source error occurs

MappingException - if an error occurs during the mapping

E extends Exception

toString

public String toString()

Overrides:

toString in class Object

getMapper

public SetRowMapper<ROW,SET,T,E> getMapper(MapperKey<K> key)
                                    throws E extends Exception

Throws:

E extends Exception
