<b>Purpose</b>: Define the EclipseLink session public interface.
<p>
<b>Description</b>: This interface is meant to clarify the public protocol into EclipseLink.
It also allows for non-subclasses of Session to conform to the EclipseLink API.
It should be used as the applications main interface into the EclipseLink API to
ensure compatibility between all EclipseLink sessions.
<p>
<b>Responsibilities</b>:
<ul>
<li> Define the API for all reading, units of work.

Returns a light weight read-only session where all
objects are automatically read as of the specified past time.
<p>Use this Session to take advantage of Oracle 9 Release 2 Flashback or
EclipseLink general history support and still be able to cache query results.
<p>A special historical session is required as all objects read may
be of different versions than those stored in the global session cache.
Hence also known as IsolationSession, as all reads bypass the global
cache.
<p>An AsOfClause at the Session level will override any clauses set at the
query or expression levels.
<p>
Example: Using a historical session to read past versions of objects.
<blockquote><pre>
AsOfClause pastTime = new AsOfClause(System.currentTimeMillis() - 24*60*60*1000);
Session historicalSession = session.acquireSessionAsOf(pastTime);
Employee pastEmployee = (Employee)historicalSession.readObject(Employee.class);
Address pastAddress = pastEmployee.getAddress();
Vector pastProjects = pastEmployee.getProjects();
historicalSession.release();
</pre></blockquote>
<p>
Example: Using the above past employee to recover objects.
<blockquote><pre>
UnitOfWork uow = baseSession.acquireUnitOfWork();
Employee presentClone = (Employee)uow.readObject(pastEmployee);
uow.deepMergeClone(pastEmployee);
uow.commit();
</pre></blockquote>
<p>
By definition all data as of a past time is frozen. So this session is
also ideal for read consistent queries and read only transactions, as all
queries will be against a consistent and immutable snap shot of the data.</div>
