Description

Interface Summary

FetchConfiguration	Allows configuration and optimization of how objects are loaded from the data store.
KodoExtent	Extension of the Extent interface that adds some Kodo-specific methods.
KodoPersistenceManager	Interface implemented by Kodo persistence managers.
KodoPersistenceManagerFactory	Interface implemented by Kodo persistence manager factories.
KodoPersistenceManagerSPI	Internal persistence manager interface.
KodoStateManager	Interface implemented by Kodo state managers.
KodoStateManagerSPI	Internal state manager interface.
LockManager	Handles obtaining and releasing locks on objects.
PCData	Holds data about a single persistence capable instance.
PCResultObjectProvider	Variant of ResultObjectProvider that populates a KodoStateManager object in an application-defined manner.
PostAttachCallback	Interface that marks a persistent class as one that should receive notification that it was attached.
PostDetachCallback	Interface that marks a persistent class as one that should receive notification that it was detached.
PreAttachCallback	Interface that marks a persistent class as one that should receive notification that it is about to be attached.
PreDetachCallback	Interface that marks a persistent class as one that should receive notification that it is about to be detached.

InverseManager	Class which manages inverse relations before flushing to the datastore.
JDOState	Base class for all JDO lifecycle states.
KodoHelper	Helper methods for acquiring PersistenceManagerFactory objects and obtaining information about persistence capable instances.
NoLockManager	A lock managed that does not perform any locking.
PCDataImpl
PersistenceManagerFactoryImpl	Abstract implementation of the PersistenceManagerFactory that must be subclassed for a specific runtime.
PersistenceManagerImpl	Concrete PersistenceManager for use with this common runtime.
SingleJVMExclusiveLockManager	An exclusive write single-JVM lock manager.

Package kodo.runtime Description

Common JDO Runtime Environment

This package provides a common JDO runtime environment that can be adapted for use with various data store mechanisms.

The runtime conforms to the JDO 1.0 Specification.

To create a concrete JDO implementation for a particular data store, a concrete StoreManager must be provided.
