public class MapMapping

extends AbstractMapMapping

The MapMapping holds an additional column: the key column. The value of the is accessed by setDataColumn and getDataColumn in the parent FieldMapping.

Method Detail

join

public void join(ObjectSelect sel)

Description copied from class: FieldMapping

Join this mapping to the given select statement. For basic mappings, this no-op method implementation will suffice. Secondary table mappings should override this method to do the proper join.

Overrides:

join in class FieldMapping

joinKey

public void joinKey(ObjectSelect sel)

Description copied from interface: Key

Join the key of this mapping to the given select statement.

load

public void load(StateManagerImpl sm,
                 Object[] pks,
                 int field,
                 SQLExecutionManager sqlem)
          throws SQLException

Description copied from interface: LoadSecondary

Load the value of this mapping for the given instance. Relations to other persistent types are loaded as PersistenceCapable instances.

Following copied from interface: com.solarmetric.kodo.impl.jdbc.ormapping.LoadSecondary

Parameters:

stmnt - The caller is responsible for closing the statement.

insert

protected void insert(Insert insert,
                      Object key,
                      Object value,
                      StateManagerImpl sm,
                      Object[] pks,
                      int field)

Overrides:

insert in class AbstractMapMapping

canMap

protected boolean canMap(FieldMetaData fmd,
                         ClassResolver resolver)

Overrides:

canMap in class AbstractMapMapping

install

protected void install(FieldMetaData fmd,
                       JDBCConfiguration conf,
                       ClassResolver resolver,
                       DBDictionary dict)

Overrides:

install in class AbstractMapMapping
