[Jboss-dev-forums] [Design of JTA and JTS on JBoss] - Re: TransactionLocalDelegateImpl

[<ad...@jb...>]

The difference is in the implementation details:

TransactionLocal

  |    protected void initDelegate()
  |    {
  |       if (transactionManager instanceof TransactionLocalDelegate)
  |          delegate = (TransactionLocalDelegate) transactionManager;
  |       else
  |          delegate = new TransactionLocalDelegateImpl(transactionManager);
  |    }
  | 

It could equally use the passed TransactionLocal rather than the implementation
since there is a one-one correspondance.

There is one object per transaction, 
see TransactionLocalSynchronization.valuesByLocal
with the synchronization being transaction scoped.
