Update of /cvsroot/nhibernate/nhibernate/src/NHibernate/Id
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv11256/Id
Modified Files:
SequenceGenerator.cs
Log Message:
Major refactoring with NDataReader and Batcher. NHibernate now uses
an IDataReader returned from the Driver for as long as possible before
converting to a NDataReader. This has nice perf gains on the simple
performance test in the Test Fixtures.
