Interface Summary

Interface	Description
DirectWriteStore	A PersistentStore that translates model-level operations into datastore calls.
PersistentStore	An InternalEObject.EStore to establish a mapping between Resources and PersistenceBackends.
TransientStore	An InternalEObject.EStore to establish a mapping between Resources and InternalEObject.EStores in a transient context, i.e, when storing data in memory.

Class Summary

Class	Description
AbstractDirectWriteStore<P extends PersistenceBackend>	An abstract DirectWriteStore that redirects certain methods according to the instance of the encountered EStructuralFeature.
AbstractPersistentStore	The abstract implementation of a PersistentStore.
AbstractPersistentStoreDecorator	An abstract PersistentStore wrapper that delegates method calls to an internal PersistentStore.
AbstractTransientStore	A abstract TransientStore that uses collections to store data in memory.
AutocommitStoreDecorator	A PersistentStore wrapper that automatically saves modifications as calls are made.
FeatureCachingStoreDecorator	A PersistentStore wrapper that caches EStructuralFeature.
InvalidStore	PersistentStore which can be used by back-end implementations that do not provide transient layer.
IsSetCachingStoreDecorator	A PersistentStore wrapper that caches the presence of a value.
LoadedObjectCounterStoreDecorator	A PersistentStore wrapper that count the number elements used.
LoggingStoreDecorator	A PersistentStore wrapper that logs every call to its methods in the NeoLogger.
OwnedTransientStore	A TransientStore that belongs to a single EObject owner.
SizeCachingStoreDecorator	A PersistentStore wrapper that caches the size data.
SynchronizedTransientStore	A TransientStore that uses synchronized collections to store data in memory, using Collections.synchronizedMap(java.util.Map).

Package fr.inria.atlanmod.neoemf.data.store Description

Provides classes to map model-level operations into persistence-level operations.

NeoEMF relies on the InternalEObject.EStore interface to extend the default serialization mechanism of EMF. The PersistentStore interface extends the InternalEObject.EStore one and provides additional methods such as allInstance() computation. This interface is implemented by backend-specific classes to serialize models into the corresponding backend.

In addition, this package defines a set of store decorators that can be combined to provide additional behavior. For example, this package defines specific store decorators to cache model elements, log backend operations, or automatically commit the pending transaction. These decorators are generic and can be plugged on top of any backend-specific PersistentStore implementation.
