Description

Interface Summary

ApplicationIdTool.ObjectIdLoader	Interface implemented by metadata factories that can load non-existant object id classes.
AttributeTranslator	Instances of this interface can convert a positional index for a FieldMetaData that uses property access into the underlying field name.
DynamicPersistenceCapable	Instances that implement this marker interface are dynamically-generated subtypes of managed types that were loaded before being enhanced.
DynamicStorage	Interface for dynamically generated classes.
FieldConsumer	Consumes persistent field values.
FieldManager	Manages persistent fields.
FieldSupplier	Supplies persistent field values.
ManagedInstanceProvider	Instances of this interface can provide an underlying instance.
PCDataGenerator.DynamicPCData	Dynamic PCDatas generated will implement this interface to simplify initialization.
PCEnhancer.AuxiliaryEnhancer	Plugin interface for additional enhancement.
PCRegistry.RegisterClassListener	Listener for persistent class registration events.
PersistenceCapable	The interface that persistent instances will implement.
RuntimeUnenhancedClassesModes	Possible values for the openjpa.RuntimeUnenhancedClasses configuration setting.
RuntimeUnenhancedClasssesModes	Possible values for the openjpa.RuntimeUnenhancedClasses configuration setting.
StateManager	Internal state manager for managed instances.

Class Summary

ApplicationIdTool	Generates a class appropriate for use as an application identity class.
ApplicationIdTool.Flags	Run flags.
ClassRedefiner	Redefines the method bodies of existing classes.
CodeGenerator	Generates Java class code from metadata.
DynamicStorageGenerator	Factory for creating new DynamicStorage classes.
InstrumentationFactory	Factory for obtaining an Instrumentation instance.
ManagedClassSubclasser	Redefines the method bodies of existing unenhanced classes to make them notify state managers of mutations.
PCClassFileTransformer	Transformer that makes persistent classes implement the PersistenceCapable interface at runtime.
PCDataGenerator	Generates PCDataGenerator.DynamicPCData instances which avoid primitve wrappers to optimize memory use and performance at the cost of slightly higher startup time.
PCEnhancer	Bytecode enhancer used to enhance persistent classes from metadata.
PCEnhancer.Flags	Run flags.
PCEnhancerAgent	Java agent that makes persistent classes work with OpenJPA at runtime.
PCRegistry	Tracks registered persistence-capable classes.
PCSubclassValidator	Validates that a given type meets the JPA contract, plus a few OpenJPA-specific additions for subclassing / redefinition: must have an accessible no-args constructor must be a public or protected class must not be final must not extend an enhanced class all persistent data represented by accessible setter/getter methods (persistent properties) if versioning is to be used, exactly one persistent property for the numeric version data When using property access, the backing field for a persistent property must be: private set only in the designated setter, in the constructor, or in Object.clone(), readObject(ObjectInputStream), or Externalizable#readExternal(ObjectInput). read only in the designated getter and the constructor.
RedefinitionHelper	Helper methods for managed types that use method redefinition for field tracking.
ReflectingPersistenceCapable	Implementation of the PersistenceCapable interface that can handle the persistence-capable contract for instances that were not enhanced before class load time.
Reflection	Reflection utilities used to support and augment enhancement.

OpenJPA Enhancer

This package provides a bytecode enhancer used to post-process classes for use in a OpenJPA runtime. A tool for generating application identity class sourcecode is also provided.
