OpenJPA Abstract StoreManager Implementation

This package provides some infrastructure classes to help in the creation of OpenJPA drivers for new non-relational data stores.

To create support for a new data store:

• Extend AbstractStoreManager following the rules outlined in its documentation.

• Configure your org.apache.openjpa.properties file (or your resource archive configuration file) to use AbstractStoreBrokerFactory, and specify your AbstractStore extension as the org.apache.openjpa.abstractstore.AbstractStoreManager class:

  org.apache.openjpa.BrokerFactory: abstractstore
org.apache.openjpa.abstractstore.AbstractStoreManager: com.xyz.MyAbstractStoreManagerSubclass

Additionally, you can optionally extend OpenJPAConfigurationImpl to define your own configuration options, using the helper classes defined in the org.apache.openjpa.lib.conf package. To do this you must also override the AbstractStoreManager.newConfiguration method.

For a sample of how to use this package, see the org.apache.openjpa.xmlstore abstract store implementation.

OpenJPA Ant Tasks

Ant tasks for OpenJPA tools.

OpenJPA Configuration

This package provides base OpenJPA configuration interfaces.

OpenJPA Data Cache

OpenJPA's data and query caching frameworks.

OpenJPA Enterprise Extensions

This package provides enterprise extensions to the OpenJPA runtime.

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.

OpenJPA Events

This package provides some interfaces and useful implementations for OpenJPA's event notification framework. This framework allows efficient notification of object modifications and transaction changes.

OpenJPA-JDBC Ant Tasks

Ant tasks for JDBC OpenJPA tools.

OpenJPA-JDBC Configuration

This package provides JDBC configuration interfaces.

OpenJPA-JDBC Runtime Kernel

Runtime services for the JDBC OpenJPA implementation.

OpenJPA-JDBC Expression Tree

OpenJPA-JDBC ORM Metadata

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

OpenJPA-JDBC ORM Strategies

Library of mapping strategies.

OpenJPA-JDBC Schema Management

This package provides utilities for managing the schema of persistent objects stored in a relational database.

Schema components themselves are little more than standard Java beans. Helper classes are responsible for added functionality such as XML serialization/deserialization, etc.

OpenJPA-JDBC SQL Abstraction

Utilities for generating SQL.

OpenJPA Runtime Kernel

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

OpenJPA Expression Tree

JPA Query Language Support

Allow any spec or store to use JPQL.

Ant Integration

This package provides a foundation for basic Ant support.

Configuration Framework

This package provides an extendable product configuration framework.

Graph Abstraction

This package provides a graph abstraction and graph-related algorithms.

Database Connectivity

Includes an implementation of the {@link javax.sql.DataSource} APIs around a normal JDBC 1.x driver. Implements logging and the ability to customize JDBC behavior. Also includes a framework for firing and consuming JDBC-related events.

Logging

This package provides a lightweight logging interface, a simple implementation that writes logging output to the console and allows for basic log configuration, and plug-ins for the Apache Commons Logging and the Apache Log4J frameworks.

Metadata Framework

Extendable framework for metadata parsing and serializing.

Result Object Provider Framework

This package provides a framework for the lazy loading of potentially large lists of data.

General Utilities

Concurrent Utilities

XML Handling

OpenJPA Metadata

This package provides an extendable framework for parsing and caching persistence metadata. The metadata can be accessed at both enhancement time and at runtime.

OpenJPA JPA

This package provides an JPA facade to OpenJPA. All major OpenJPA runtime components have JPA-flavored facades in this package.

Tests for the JPA Cache interface

OpenJPA Criteria Query

This package provides an implementation of Criteria API in JPA 2.0 Specification and extended features such as Query-By-Example.

OpenJPA JPA-JDBC

JDBC-specific extensions to OpenJPA JPA runtime.

OpenJPA MetaModel

This package provides an implementation of Metamodel API of JPA 2.0 Specification.

OpenJPA Dynamic Query

This package provides dynamic query construction that are similar to weakly-typed Criteria API.

OpenJPA JPA Utilities

This package provides utility functions used by JPA facade to OpenJPA.

OpenJPA Utilities

This package provides utilities to facilitate the handling of second class objects and OpenJPA object ids.

XML Store

Simple XML store using the common OpenJPA runtime system as a front end.
