Interface Summary
LRSCollectionFieldStrategy Interface implemented by collection strategies so that they can support large result set collections.
LRSMapFieldStrategy Interface implemented by map strategies so that they can support large result set maps.
 

Class Summary

ClassNameDiscriminatorStrategy Stores the class name along with each database object record.
ClobValueHandler Handler for clob values.
ColumnVersionStrategy Uses a one or more column(s) and corresponding version object.
ContainerFieldStrategy An abstract container mapping that handles traversing the join to examine the size of the relation.
ElementEmbedValueHandler Handler for embedded objects as elements of a collection or map.
EmbeddedClassStrategy Class mapping for embedded objects.
EmbedFieldStrategy Mapping for an embedded persistent object.
EmbedValueHandler Base class for embedded value handlers.
EnumValueHandler Value handler for JDK1.5 enum field types.
FlatClassStrategy Mapping for classes mapped to their superclass table.
FullClassStrategy Mapping for when the class maps all fields to its own table.
HandlerCollectionTableFieldStrategy Mapping for a collection of values in a separate table controlled by a ValueHandler.
HandlerFieldStrategy Mapping for a single-valued field that delegates to a ValueHandler.
HandlerHandlerMapTableFieldStrategy Mapping for a map of keys and values both controlled by ValueHandlers.
HandlerRelationMapTableFieldStrategy Mapping for a map whose keys are controlled by a ValueHandler and whose values are relations to other persistent objects.
HandlerStrategies Utility methods for strategies using value handlers.
ImmutableValueHandler Handler for simple type and string values.
InValueDiscriminatorStrategy Base discriminator strategy that determines the class of database records using a column holding a value mapped to a class, and limits SELECTs using an IN (...) statement.
LobFieldStrategy Direct mapping from a stream value to a column.
LRSProxyCollection Large result set collection.
MapTableFieldStrategy Base class for map mappings.
MaxEmbeddedBlobFieldStrategy Mapping for serialized fields on a dictionary that has a maximum embedded BLOB size.
MaxEmbeddedByteArrayFieldStrategy Mapping for byte array fields on a dictionary that has a maximum embedded BLOB size.
MaxEmbeddedCharArrayFieldStrategy Mapping for CLOB character array on a dictionary that has a maximum embedded CLOB size.
MaxEmbeddedClobFieldStrategy Mapping for CLOB string on a dictionary that has a maximum embedded CLOB size.
MultiColumnVersionStrategy Uses multiple version numbers spanning multiple columns for optimistic versioning.
NanoPrecisionTimestampVersionStrategy Uses a timestamp for optimistic versioning with nanosecond precision.
NoneClassStrategy Strategy for classes that aren't mapped.
NoneDiscriminatorStrategy No-op Discriminator strategy.
NoneFieldStrategy An unmapped field.
NoneVersionStrategy No-op version strategy.
NumberVersionStrategy Uses a version number for optimistic versioning.
ObjectIdClassStrategy Class mapping for embedded object id fields.
ObjectIdValueHandler Handler for embedded object id fields.
PrimitiveFieldStrategy Direct mapping from a primitive value to a column.
RelationCollectionInverseKeyFieldStrategy Maps a relation to a collection of other objects using an inverse foreign key in the related object table.
RelationCollectionTableFieldStrategy Maps a collection of related objects through an association table.
RelationFieldStrategy Mapping for a single-valued relation to another entity.
RelationHandlerMapTableFieldStrategy Mapping for a map whose keys are relations to other persistent objects and whose values are controlled by a ValueHandler.
RelationMapInverseKeyFieldStrategy Uses an inverse foreign key in the table of the map value to determine map values.
RelationMapTableFieldStrategy Uses an association table to hold map values.
RelationRelationMapTableFieldStrategy Mapping for a map whose keys and values are both relations to other persistent objects.
RelationStrategies Helper methods for relation mappings.
RelationToManyInverseKeyFieldStrategy Maps a relation to a set of other objects using an inverse foreign key in the related object table.
RelationToManyTableFieldStrategy Maps a set of related objects through an association table.
StateComparisonVersionStrategy Uses a state image to determine whether concurrency violations take place.
StateComparisonVersionStrategy.CustomUpdate Row implementation we use to pass to versionable mappings so they can set up the where conditions we need to add to update statements.
StoreCollectionFieldStrategy Base class for strategies that are stored as a collection, even if their field value is something else.
StringFieldStrategy Direct mapping from a string value to a column.
SubclassJoinDiscriminatorStrategy Discriminator strategy that outer joins to all possible subclass tables to determine the class of an instance.
SuperclassDiscriminatorStrategy Discriminator strategy that delegates to superclass discriminator.
SuperclassVersionStrategy Version strategy that delegates to the suerpclass version.
TimestampVersionStrategy Uses a timestamp for optimistic versioning.
UntypedPCValueHandler Handler for unknown persistence-capable object fields that stores stringified oids.
ValueMapDiscriminatorStrategy Maps metadata-given values to classes.
VerticalClassStrategy Mapping for subclasses that join to their superclass table.
XMLValueHandler Base class for xml value handlers.
