BerkeleyDbConfig	A Config that creates BerkeleyDB specific configuration.

Package fr.inria.atlanmod.neoemf.data.berkeleydb.config Description

Provides configuration classes to define specific behaviors of BerkeleyDB data persistence.

This package defines the configuration by extending Config: fr.inria.atlanmod.neoemf.data.mapdb.config.BerkeleyDbConfig is a fluent API allowing to easily set BerkeleyDB specific mapping configuration in client applications. Since the configuration implements Config it can be used to combiner BerkeleyDB specific and generic configuration.

These classes are used to create option maps used in EMF save and load methods. For example, the following code creates a map that tells the framework to use a BerkeleyDB backend with an explicit representation of collection indices, and a cache the accessed features to retrieve them efficiently. The explicit indice representation is a BerkeleyDB specific option, while the caching behavior is defined at the core level.

 // Create the option map
 Map<String, Object> options = new BerkeleyDbConfig()
     .withIndices()
     .cacheFeatures()
     .toMap();

 // Load the resource with the specified options
 myResource.load(options);

 // Manipulate the resource with a BerkeleyDB backend representing explicitly collection indices and feature cache
 enabled
 myResource.getContents() [...]
