CollectionFieldMapping

public CollectionFieldMapping(FieldMetaData meta)

Constructor. Supply underlying metadata.

Method Detail

getMappingType

public String getMappingType()

Description copied from interface: Mapping

Return the abbreviated name of this mapping, or the full class name if it is a custom mapping.

fromMappingInfo

public void fromMappingInfo(MappingInfo info,
                            boolean adapt)

Description copied from class: AbstractFieldMapping

The default implementation will raise warnings for any mapping attributes that are declared but not in the list of the valid attributes for this mapping.

Overrides:

fromMappingInfo in class ColumnCollectionFieldMapping

Following copied from class: kodo.jdbc.meta.AbstractFieldMapping

See Also:

AbstractFieldMapping.addMappingInfoAttributes(java.util.Collection)

map

public boolean map()

Description copied from interface: Mapping

Map a new instance of this mapping type. If the underlying metadata cannot be mapped using this type, return false.

Overrides:

map in class ColumnCollectionFieldMapping

reverseMap

public void reverseMap(SchemaGroup schema,
                       ReverseMappingTool tool)

Description copied from interface: Mapping

Create mappings from the schema, using the given tool. Implement this method if you want the class mapping to be a candidate when reverse-mapping a schema to java classes. Note that this method will be invoked on a template instance, so you cannot rely on the metadata or owning repository being set.

Overrides:

reverseMap in class AbstractFieldMapping

isCollectionTable

public static boolean isCollectionTable(Table table,
                                        ReverseMappingTool tool)

Return true if the given table matches the pattern for a collection table.

selectEager

public void selectEager(Select sel,
                        KodoStateManager sm,
                        JDBCStoreManager store,
                        JDBCFetchConfiguration fetch)

Description copied from interface: FieldMapping

Select eager to-many relations. This method is only called under; default.

Overrides:

selectEager in class AbstractFieldMapping

Following copied from interface: kodo.jdbc.meta.FieldMapping

Parameters:

sel - the select to add to

sm - the instance being loaded, or null if not initialized yet or selecting for multiple instances

store - the current store manager

fetch - fetch configuration

load

public void load(KodoStateManager sm,
                 JDBCStoreManager store,
                 JDBCFetchConfiguration fetch,
                 Result res)
          throws SQLException

Description copied from class: ContainerFieldMapping

Loads the metadata.

Overrides:

load in class ContainerFieldMapping

loadProjection

public Object loadProjection(JDBCStoreManager store,
                             JDBCFetchConfiguration fetch,
                             Result res)
                      throws SQLException

Description copied from interface: FieldMapping

Load this field value using the given result. This method will only be called if this field does not represent a FCO relation. The result will contain the columns from FieldMapping.getColumns().
