Examples of org.prevayler.TransactionWithQuery

org.prevayler.TransactionWithQuery
A Transaction that also returns a result or throws an Exception after executing.

A "PersonCreation" Transaction, for example, may return the Person it created. Without this, to retrieve the newly created Person, the caller would have to issue a Query like: "What was the last Person I created?".

Looking at the Prevayler demos is by far the best way to learn how to use this class. @param < P> The type or any supertype of the Prevalent System you intend to perform the transaction and query upon.
@param < R> The type of object which should be returned.

        Serializable result;
        TransactionWithQuery transaction = (TransactionWithQuery) t;
        try {
          result = (Serializable) prevayler.execute(transaction);
        } catch (Exception e) {
          result = new ThrownException(e);
