@ParametersAreNonnullByDefault
public final class BoundInMemoryBackend
extends AbstractInMemoryBackend

A InMemoryBackend, bound to a unique Id, that stores all elements in Maps.

This Backend is fully transient and used when a PersistentEObject is not owned by a Resource, persistent or not.

For performance reason, each instance is bound to a unique Id, but data are stored in maps shared between all instances.
