Class TransactionDataImpl<T extends TransactionData>

  • All Implemented Interfaces:
    TransactionData
    public class TransactionDataImpl<T extends TransactionData>
extends java.lang.Object
implements TransactionData
    Hold data accumulated during a transaction which we want to persist just prior to commit. Because multiple datasources could be involved in a distributed transaction, we need to hold TransactionData for each. Note that because all of this relates to a single transaction, this also means that it's a single thread, so there are no concurrency issues.
