Class Summary

AbstractClassMapping	Mapping from a class to a relational schema.
AbstractCollectionFieldMapping	Base class for collection mappings.
AbstractFieldMapping	Maps a persistent field to the relational schema.
AbstractMapFieldMapping	Base class for map mappings.
BaseClassMapping	Class mapping used for base classes in a persistent inheritance tree.
BlobFieldMapping	Maps a single-column BLOB.
ByteArrayFieldMapping	Maps a single-column unserialized BLOB.
ClassIndicator	Handles determining the object class of database records.
ClassMappingInfo	Holds information about a class mapping; this is used as an intermediate step during serialization and deserialization of ClassMappings to XML or some other format.
ClobFieldMapping	Maps a CLOB.
CollectionFieldMapping	Maps a collection of simple values.
ColumnClassIndicator	Abstract base class for class indicators that use a column to hold class information.
ColumnCollectionFieldMapping	Base type for collection mappings that use a single column for their element value.
ColumnFieldMapping	Base class for single-column mappings.
ColumnMapFieldMapping	A map where both the key and value are single-column mappings.
ColumnToManyMapFieldMapping	Maps a map of single-column keys to related objects.
ColumnVersionIndicator	Abstract base class for version indicators that use a column to hold version information.
ContainerFieldMapping	Base class for collection and map mappings.
DateVersionIndicator	Handles optimistic lock versioning via a lock column containing timestamps in the data store.
DBMappingFactory	Factory that uses an XML mapping definition stored in the database to record the system mappings.
DelegatingJoinableMapping	Delegates to another JoinableMapping after doing column translation.
EmbeddedOneToOneFieldMapping	Maps an embedded 1-1 relation.
FieldMappingInfo	Holds information about a field mapping; this is used as an intermediate step during serialization and deserialization of FieldMappings to XML or some other format.
FileMappingFactory	Factory that uses multiple XML mapping files to construct the system mappings.
FlatClassMapping	Mapping for subclasses that are stored in their parent class' table.
HorizontalClassMapping	Mapping that relies on subclass mappings to define the fields.
InClassNameClassIndicator	Determines the class of database records using a column holding the class name, and limits SELECTs using an IN (...) statement.
Indicator	Base class for class and version indicators.
InValueClassIndicator	Base class indicator that determines the class of database records using a column holding a value mapped to a class, and limits SELECTs using an IN (...) statement.

ManyToPCObjectMapFieldMapping	A map where the keys are related objects and the values are unknown persistent objects.
MapFieldMapping	Maps a map of simple values.
MappingInfo	Base class for ClassMappingInfo and FieldMappingInfo.
MappingInfoRepository	Simple repository for ClassMappingInfos.
MappingRepository	Repository of class mapping information.
Mappings	Mapping helper class.

MetaDataMappingFactory	Factory that places mapping information in JDO metadata extensions.
MetaDataValueClassIndicator	Determines the class of database records using a metadata extensions that map a database value to the class it represents.
NoneClassMapping	Placeholder mapping for classes that indicate they do not need a mapping because they are never persisted directly.
NoneFieldMapping	Placeholder mapping for non-persistent fields or fields that do not need mappings.
NToManyMapFieldMapping	Maps a map of simple keys to related objects.
NToPCObjectMapFieldMapping	A map where the keys are simple values and the values are unknown persistent objects.
NumberVersionIndicator	Handles optimistic lock versioning via a lock column containing numeric version numbers in the data store.

OneToOneFieldMapping	Maps a relation to another object.
PCObjectCollectionFieldMapping	Maps a collection of unknown persistent objects.
PCObjectMapFieldMapping	A map where both the keys and values are unknown persistent objects.
PCObjectOneToOneFieldMapping	Maps a 1-1 relation to an unknown persistent object.
PCObjectToManyMapFieldMapping	A map where both the keys are unknown persistent objects and the values are related objects.
PCObjectToNMapFieldMapping	A map where the keys are unknown persistent objects and the values are simple values.
PropertiesReverseCustomizer	Simple ReverseCustomizer that uses a properties file to to allow customization of basic class and field properties.
ReferenceFieldMapping	Base class of most field mappings.
ReverseMappingTool	Reverse-maps a schema into class mappings and the assiciated java code.
StateImageVersionIndicator	Bases versioning on the values of the object's persistent state.
SubclassJoinClassIndicator	Class indicator that outer joins to all possible subclass tables to determine the class of an instance.
TransformationFieldMapping	Easily-extendable mapping for transforming a field value from one simple type to another.
ValueFieldMapping	Maps a single-column value.
VersionIndicator	Handles optimistic lock versioning for a class.
VerticalClassMapping	Mapping for classes that use a separate primary table than their parent class.
VirtualFieldMapping	Placeholder mapping for virtual fields that are unmapped by the superclass.
