Method Detail

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 OneToOneMapping

installOneToOneMapping

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

Overrides:

installOneToOneMapping in class OneToOneMapping

isInverse

public boolean isInverse()

Overrides:

isInverse in class OneToOneMapping

select

public void select(Select sel)

Description copied from interface: LoadPrimary

Select the value of this mapping.

Overrides:

select in class OneToOneMapping

load

public void load(StateManagerImpl sm,
                 int field,
                 ResultSet rs,
                 int startColumn)
          throws SQLException

Description copied from interface: LoadPrimary

Load the value of this mapping from the ResultSet produced by the Select passed to the LoadPrimary.select(com.solarmetric.kodo.impl.jdbc.sql.Select) method.

Overrides:

load in class OneToOneMapping

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.

Overrides:

load in class OneToOneMapping

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

Parameters:

stmnt - The caller is responsible for closing the statement.

insert

public void insert(Insert insert,
                   StateManagerImpl sm,
                   int field)
            throws SQLException

Description copied from interface: StorePrimary

Insert the given field into the primary table for this mapping.

Overrides:

insert in class OneToOneMapping

update

public void update(Update update,
                   StateManagerImpl sm,
                   int field)
            throws SQLException

Description copied from interface: StorePrimary

Update the given field into the primary table for this mapping.

Overrides:

update in class OneToOneMapping

delete

public void delete(Delete del,
                   StateManagerImpl sm,
                   int field)
            throws SQLException

Description copied from interface: StorePrimary

Delete the field from the primary table for this mapping.

Overrides:
