ClassResolver	Interface to customize the loading of classes under OpenJPA.
CollectionChangeTracker	Change tracker that can be used for collections.
ExceptionInfo	Interface supplying additional exception information.
LRSProxy	Marker interface for large result set proxies.
MapChangeTracker	Change tracker that can be used for maps.
Proxy	Interface implemented by all proxy types to allow setting and nulling of their owning instance.

Class Summary

AbstractChangeTracker	Base class that provides utilities to change trackers.
AbstractLRSProxyCollection	A collection proxy designed for collections backed by extremely large result sets in which each call to AbstractLRSProxyCollection.iterator() may perform a database query.
AbstractLRSProxyMap	A map proxy designed for maps backed by extremely large result sets in which each call to AbstractLRSProxyMap.get(java.lang.Object) or AbstractLRSProxyMap.containsKey(java.lang.Object) may perform a database query.
ApplicationIds	Utility class for manipulating application object ids.
ArrayStateImage	Utilities for dealing with a simple state image consisting of an Object[] of field values with one extra index containing a BitSet of loaded fields.
ByteId	OpenJPAId subclass appropriate for byte fields.
CacheMap	Fixed-size map that has ability to pin/unpin entries and move overflow to a backing soft map.
CharId	OpenJPAId subclass appropriate for char fields.
ClassResolverImpl	Default class resolver implementation.
CollectionChangeTrackerImpl	Default CollectionChangeTracker.
DateId	OpenJPAId subclass appropriate for Date fields.
Exceptions	Utility methods for externalizing and handling exceptions.
Id	Datastore identity type.
ImplHelper	Helper for OpenJPA back-ends.
IntId	OpenJPAId subclass appropriate for int fields.
LongId	OpenJPAId subclass appropriate for long fields.
MapChangeTrackerImpl	Default MapChangeTracker.
MultiLoaderClassResolver	A simple ClassResolver that uses multiple class loaders to resolve classes.
ObjectId	Identity type appropriate for object primary key fields and shared id classes.
OpenJPAId	Identity class extended by builtin OpenJPA identity objects.
Proxies	Utility methods for managing proxies.
ProxyArrayList	Extension of the ArrayList type that dirties the persistent/transactional field it is assigned to on modification.
ProxyGregorianCalendar	Extension of the Calendar type that calls the dirty method on its owning persistence capable instance on modification.
ProxyGregorianCalendar4	ProxyGregorianCalendar subclass that overrides the mutating ProxyGregorianCalendar4.set(int, int) method, which is final in Java 1.3 but public in Java 1.4 and higher.
ProxyHashMap	Extension of the HashMap type that dirties the persistent/transactional field it is assigned to on modification.
ProxyHashSet	Extension of the HashSet type that dirties the persistent/transactional field it is assigned to on modification.
ProxyHashtable	Extension of the Hashtable type that dirties the persistent/transactional field it is assigned to on modification.
ProxyLinkedList	Extension of the LinkedList type that dirties the persistent/transactional field it is assigned to on modification.
ProxyManagerImpl	Default implementation of the ProxyManager interface.
ProxyProperties	Extension of the Properties type that dirties the persistent/transactional field it is assigned to on modification.
ProxySQLDate	Extension of the Date type that calls the dirty method on its owning persistence capable instance on modification.
ProxyTime	Extension of the Time type that calls the dirty method on its owning persistence capable instance on modification.
ProxyTimestamp	Extension of the Timestamp type that calls the dirty method on its owning persistence capable instance on modification.
ProxyTreeMap	Extension of the TreeMap type that dirties the persistent/transactional field it is assigned to on modification.
ProxyTreeSet	Extension of the TreeSet type that dirties the persistent/transactional field it is assigned to on modification.
ProxyUtilDate	Extension of the Date type that calls the dirty method on its owning persistence capable instance on modification.
ProxyVector	Extension of the Vector type that dirties the persistent/transactional field it is assigned to on modification.
Serialization	Helper class to serialize and deserialize persistent objects, subtituting oids into the serialized stream and subtituting the persistent objects back during deserialization.
ShortId	OpenJPAId subclass appropriate for short fields.
StoreFacadeTypeRegistry	Repository of store-specific facade classes.
StringId	OpenJPAId subclass appropriate for String fields.

Exception Summary

CallbackException	Exception type thrown when an error occurs in a callback.
GeneralException	General exception type.
InternalException	Exception type for internal errors.
InvalidStateException	Exception type thrown when attempting to execute an operation that is not allowed by the current state.
LockException	Exception indicating that locks on one or more objects could not be acquired.
MetaDataException	Exception type reserved for missing or invalid metadata.
NoTransactionException	Exception type thrown when attempting a transactional operation without an active transaction.
ObjectExistsException	Exception type reserved for conflicts with existing objects.
ObjectNotFoundException	Exception type reserved for failed object lookups.
