oracle.toplink.essentials.internal.sessions.DatabaseSessionImpl

Implementation of oracle.toplink.essentials.sessions.DatabaseSession The public interface should be used by public API, the implementation should be used internally. @see oracle.toplink.essentials.sessions.DatabaseSession

Purpose: Define the implementation for a single user/single connection TopLink 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. The database session is intended for usage in two-tier client-server applications. Although it could be used in a server situation, it is limitted to only having a single database connection and only allows a single open database transaction.

Responsibilities:

Connecting/disconnecting.
Reading and writing objects.
Transaction and unit of work support.
Identity maps and caching.

        StringWriter writer = new StringWriter();
        writer.write(Helper.getShortClassName(getClass()));
        writer.write("(");


        try {
            DatabaseCall call = buildCall(new DatabaseSessionImpl(new oracle.toplink.essentials.sessions.DatabaseLogin()));
            writer.write(call.getSQLString());
        } catch (Exception exception) {
        }
        writer.write(")");

     * This returns an implementor of the DatabaseSession interface, which can be used to login
     * and add descriptors from other projects.  The Session interface however should be used for
     * reading and writing once connected for complete portability.
