Examples of AbstractSession

net.timewalker.ffmq3.common.session.AbstractSession

Base implementation for a JMS {@link Session}
oracle.toplink.essentials.internal.sessions.AbstractSession
Implementation of oracle.toplink.essentials.sessions.Session The public interface should be used by public API and testing, the implementation should be used internally. @see oracle.toplink.essentials.sessions.Session
Purpose: Define the interface and common protocol of a TopLink compliant session.
Description: The session is the primary interface into TopLink, the application should do all of its reading and writing of objects through the session. The session also manages transactions and units of work. Normally the session is passed and used by the application controler objects. Controler objects normally sit behind the GUI and perform the buiness processes required for the application, they should perform all explict database access and database access should be avoided from the domain object model. Do not use a globally accessable session instance, doing so does not allow for multiple sessions. Multiple sessions may required when performing things like data migration or multiple database access, as well the unit of work feature requires the usage of multiple session instances. Although session is abstract, any users of its subclasses should only cast the variables to Session to allow usage of any of its subclasses.
Responsibilities:
- Connecting/disconnecting.
- Reading and writing objects.
- Transaction and unit of work support.
- Identity maps and caching.

org.apache.sshd.common.session.AbstractSession
The AbstractSession handles all the basic SSH protocol such as key exchange, authentication, encoding and decoding. Both server side and client side sessions should inherit from this abstract class. Some basic packet processing methods are defined but the actual call to these methods should be done from the {@link #handleMessage(org.apache.sshd.common.util.Buffer)}method, which is dependant on the state and side of this session. TODO: if there is any very big packet, decoderBuffer and uncompressBuffer will get quite big and they won't be resized down at any time. Though the packet size is really limited by the channel max packet size @author Apache MINA SSHD Project
org.cafesip.sipunit.AbstractSession
org.eclipse.jetty.server.session.AbstractSession

Implements {@link javax.servlet.http.HttpSession} from the javax.servlet package.
org.eclipse.persistence.internal.sessions.AbstractSession
Implementation of org.eclipse.persistence.sessions.Session The public interface should be used. @see org.eclipse.persistence.sessions.Session
Purpose: Define the interface and common protocol of an EclipseLink compliant session.
Description: The session is the primary interface into EclipseLink, the application should do all of its reading and writing of objects through the session. The session also manages transactions and units of work. Normally the session is passed and used by the application controller objects. Controller objects normally sit behind the GUI and perform the business processes required for the application, they should perform all explicit database access and database access should be avoided from the domain object model. Do not use a globally accessible session instance, doing so does not allow for multiple sessions. Multiple sessions may required when performing things like data migration or multiple database access, as well the unit of work feature requires the usage of multiple session instances. Although session is abstract, any users of its subclasses should only cast the variables to Session to allow usage of any of its subclasses.
Responsibilities:
- Connecting/disconnecting.
- Reading and writing objects.
- Transaction and unit of work support.
- Identity maps and caching.
