Package org.apache.openjpa.jdbc.meta

OpenJPA-JDBC ORM Metadata

This package extends the standard persistence metadata with object-relational mapping information.

Interface Summary

Interface	Description
ClassStrategy	Mapping from a class to a relational schema.
DiscriminatorStrategy	Handles determining the object class of database records.
Embeddable	Interface for field strategies that can managed fields of embedded-element, embedded-key, and embedded-value objects.
FieldStrategy	Maps a persistent field to the relational schema.
Joinable	Represents a value that can be joined to.
MappingDefaults	Generates default names for tables, columns, indexes, constraints, etc.
MappingInfo.ForeignKeyDefaults	Supplies default foreign key information.
MappingInfo.TableDefaults	Supplies default table information.
MappingTool.ImportExport	Helper used to import and export mapping data.
RelationId	Callback to store a relation after the object id has been assigned.
ReverseCustomizer	Plugin in interface to customize the output of the ReverseMappingTool.
Strategy	Interface implemented by all mapping strategies.
ValueHandler	Maps a value to a relational schema.
ValueMapping	Specialization of value metadata for relational databases.
VersionStrategy	Handles optimistic lock versioning for a class.

Class Summary

Class	Description
ClassMapping	Specialization of metadata for relational databases.
ClassMappingInfo	Information about the mapping from a class to the schema, in raw form.
DelegatingJoinable	Delegates to another Joinable after doing column translation.
Discriminator	Handles determining the object class of database records.
DiscriminatorMappingInfo	Information about the mapping from a discriminator to the schema, in raw form.
FieldMapping	Specialization of metadata for relational databases.
FieldMappingInfo	Information about the mapping from a field to the schema, in raw form.
JavaSQLTypes	Java SQL type constants.
MappingDefaultsImpl	Default implementation of MappingDefaults.
MappingInfo	Base class storing raw mapping information; defines utility methods for converting raw mapping information to full mapping to the schema.
MappingRepository	Repository of object/relational mapping information.
MappingStrategyInstaller	Installer used during mapping that attempts to use the given mapping information (if any), and fails if it does not work.
MappingTool	Tool for manipulating class mappings and associated schema.
MappingTool.Flags	Run flags.
MetaDataPlusMappingFactory	Combines two internal MetaDataFactory instances -- one for metadata, one for mappings -- into a single MetaDataFactory facade.
NoneMappingDefaults	No-op mapping defaults.
NoneStrategyInstaller	Clears all mapping information from classes and installs none strategies.
PropertiesReverseCustomizer	Simple ReverseCustomizer that uses a properties file to to allow customization of basic class and field properties.
QueryResultMapping	Mapping of a query result set to scalar and/or persistence-capable object-level values.
RefreshStrategyInstaller	Attempts to install using the given mapping information.
ReverseMappingTool	Reverse-maps a schema into class mappings and the associated java code.
ReverseMappingTool.Flags	Holder for run flags.
RuntimeStrategyInstaller	Installer that attempts to use the given mapping information, and fails if it does not work.
SequenceMapping	Specialization of sequence metadata for ORM.
StrategyInstaller	Installs mapping strategies.
ValueMappingImpl	Standalone ValueMapping implementation.
ValueMappingInfo	Information about the mapping from a field value to the schema, in raw form.
Version	Handles optimistic lock versioning for a class.
VersionMappingInfo	Information about the mapping from a version indicator to the schema, in raw form.
