Extent<E>	Instances of the Extent class represent the entire collection of instances in the data store of the candidate class or interface possibly including its subclasses or subinterfaces.
FetchGroup	FetchGroup represents a named fetch group for a specific class or interface.
FetchPlan	Fetch groups are activated using methods on this interface.
InstanceCallbacks	A PersistenceCapable class that provides callback methods for life cycle events implements this interface.
JDOEnhancer	Interface for a JDO Enhancer.
JDOQLTypedQuery<T>	Interface for a type-safe refactorable JDOQL query, using a fluent API, based around expressions.
JDOQLTypedSubquery<T>	Interface for a type-safe subquery, using a fluent API.
PersistenceManager	PersistenceManager is the primary interface for JDO-aware application components.
PersistenceManagerFactory	The PersistenceManagerFactory is the interface to use to obtain PersistenceManager instances.
Query<T>	The Query interface allows applications to obtain persistent instances, values, and aggregate data from the data store.
Transaction	The JDO Transaction interface provides for initiation and completion of transactions under user control.

Class Summary

Class	Description
AttributeConverter.UseDefault	Dummy converter to represent "use the implementation default for this type" when using annotations.
Enhancer	Main class to invoke a JDO Enhancer.
JDOHelper	This class can be used by a JDO-aware application to call the JDO behavior of PersistenceCapable instances without declaring them to be PersistenceCapable.

Enum Summary

Enum	Description
ObjectState	This class defines the object states for JDO instances.

Exception Summary

Exception	Description
JDOCanRetryException	This is the base class for exceptions that can be retried.
JDODataStoreException	This class represents data store exceptions that can be retried.
JDODetachedFieldAccessException	This class represents exceptions caused by access of an unloaded field while the instance is detached.
JDOEnhanceException	Exception thrown when an error occurs during enhancement.
JDOException	This is the root of all JDO Exceptions.
JDOFatalDataStoreException	This class represents data store exceptions that cannot be retried.
JDOFatalException	This class represents exceptions that are fatal; that is, the condition that caused it cannot be bypassed even if the operation is retried.
JDOFatalInternalException	This class represents errors in the implementation for which no user error handling is possible.
JDOFatalUserException	This class represents user errors that cannot be retried.
JDONullIdentityException	An instance of this class is thrown when attempting to create an object id when the object id constructor parameter is null.
JDOObjectNotFoundException	This class represents exceptions caused by the user accessing an object that does not exist in the datastore.
JDOOptimisticVerificationException	This class represents optimistic verification failures.
JDOQueryInterruptedException	This class represents exceptions caused when a query is cancelled by a user calling Query.cancel().
JDOReadOnlyException	This class represents exceptions caused by an attempt to update a datastore when the PMF was created as "read-only".
JDOUnsupportedOptionException	This class represents exceptions caused by the use of optional features not supported by the JDO implementation.
JDOUserCallbackException	This class represents exceptions caused by exceptions thrown during execution of callbacks or listeners.
JDOUserException	This class represents user errors that can possibly be retried.
