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)

Description copied from class: FieldMapping

Return true if this mapping type can handle the given field, false otherwise. Note that this method cannot rely on the existance of other Mappings, as it is used in bootstrapping.

Overrides:

canMap in class AbstractMapMapping

install

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

Description copied from class: FieldMapping

Setup this FieldMapping using the given metadata. Note that this method cannot rely on the existance of other Mappings, as it it is used in bootstrapping. This base implementation installs the proper extensions onto the metadata only; subclasses must override to properly map the type.

Overrides:

install in class AbstractMapMapping

joinRelation

public void joinRelation(Joins joins,
                         PersistenceManagerImpl pm)

Description copied from class: FieldMapping

Join this value's table to the table for the related first class object type, if any.

Overrides:

joinRelation in class FieldMapping

joinKeyRelation

public void joinKeyRelation(Joins joins,
                            PersistenceManagerImpl pm)

Description copied from class: FieldMapping

Join this value's table to the table for the related first class object key type, if any.

Overrides:

joinKeyRelation in class FieldMapping
