[Nhibernate-commit] nhibernate/src/NHibernate/Id SequenceGenerator.cs,1.4,1.5

[Michael D. <mik...@us...>]

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.
