org.eclipse.persistence.sessions.server.ServerSession
Implementation of Server INTERNAL: The public interface should be used.
Purpose: A single session that supports multiple user/clients connection at the same time.
Description: This session supports a shared session that can be used by multiple users or clients in a three-tiered application. It brokers client sessions to allow read and write access through a unified object cache. The server session provides a shared read only database connection that is used by all of its client for reads. All changes to objects and the database must be done through a unit of work acquired from the client session, this allows the changes to occur in a transactional object space and under a exclusive database connection.
Responsibilities:
- Connecting/disconnecting the default reading login.
- Reading objects and maintaining the object cache.
- Brokering client sessions.
- Disabling database modification through the shared connection.
