All Implemented Interfaces:

LoadSecondary, Relation

public class OneToManyMapping

extends AbstractCollectionMapping

implements Relation, LoadSecondary

Represents a 1-M relation with a persistent object type, where the related persistent type has a 1-1 relation back to the owning type of this FieldMapping. Thus, a 1-M mapping does not store any data itself, and instead relies on the columns of the related type.

OneToManyMapping

public OneToManyMapping()

Method Detail

getRelationType

public Class getRelationType()

Description copied from interface: Relation

Return the type the mapping relates to.

Specified by:

getRelationType in interface Relation

getRelationPKColumns

public Column[] getRelationPKColumns()

Description copied from interface: Relation

Return the primary key column(s) of the related object.

Specified by:

getRelationPKColumns in interface Relation

setRelationPKColumns

public void setRelationPKColumns(Column[] val)

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

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.

Specified by:

load in interface LoadSecondary

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

Parameters:

stmnt - The caller is responsible for closing the statement.

canMap

protected boolean canMap(FieldMetaData fmd,
                         ClassResolver resolver)

install

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