Class NoClientTransactions

java.lang.Object
  org.modeshape.jcr.txn.Transactions
      org.modeshape.jcr.txn.NoClientTransactions

public class NoClientTransactions
extends Transactions

An implementation of Transactions that does not even check whether there is a current transaction and instead always attempts to create a transaction within the SessionCache.save() calls. This is more efficient when the repository can be set up to never use container-managed or user-managed transactions.
