Module org.cumulus4j.store

Plug-in for DataNucleus providing encrypted data-storage.

It is responsible for storing data in an encrypted form as well as querying the data (JDOQL or JPAQL are supported). Therefore, it uses a backend-datastore (accessed via DataNucleus over the JDO API) in which it manages its own data structure. Additionally to using only one single backend-datastore, the usage of two separate datastores (one for indexes and one for the actual data) is supported, too.

DataNucleus uses the Eclipse plugin-mechanism and this plug-in is the core of Cumulus4j containing extensions to the following DN extension-points:

org.datanucleus.member_annotation_handler
org.datanucleus.persistence_properties
org.datanucleus.store_connectionfactory
org.datanucleus.store_manager
org.datanucleus.store_query_query
org.datanucleus.store_valuegenerator

In order to be extensible, this plug-in itself declares a few extension-points:

org.cumulus4j.store.crypto_manager (see CryptoManager)
- Extension provided by org.cumulus4j.store.crypto.keymanager
org.cumulus4j.store.index_mapping (see IndexEntry)
org.cumulus4j.store.query_method (see MethodEvaluator)

These lists might not be up-to-date, but they should give you an idea (check the plugin.xml, if you want to be sure).

Maven

After adding the repositories documented on the Download page to your pom.xml, you can add the following dependency in order to use this module:

<dependencies>
        ...
        <dependency>
                <groupId>org.cumulus4j</groupId>
                <artifactId>org.cumulus4j.store</artifactId>
        </dependency>
        ...
</dependencies>

The above dependency does not (and should not!) declare a version. Instead, it is recommended that you add the following to your dependency-management:

<dependencyManagement>
        <dependencies>
                ...
                <dependency>
                        <groupId>org.cumulus4j</groupId>
                        <artifactId>org.cumulus4j.parent</artifactId>
                        <type>pom</type>
                        <version>1.1.0</version>
                        <scope>import</scope>
                </dependency>
                ...
        </dependencies>
</dependencyManagement>
