Regarding java xmlmanager and transactions

Question

xmlmanager has a prepare function that takes in an xmltransaction as a parameter and returns a xmlqueryexpression. if i prepare a query expression object with the prepare function and an xmltransaction object, can i safely reuse that xmlqueryexpression object with a different xmltransaction object?
thanks.

Answer 1

I think that's OK but the xmlqueryexpression object should be reused AFTER the expression object has been prepare by XmlTransaction::commit() sucessfully .
For example:
XmlTransaction txn1 = mgr.creatTransaction();
std::string query = <The query expression>;
XmlExpression expr = mgr.prepare(txn1, query, qc);
txn1.commit();
XmlQueryContext qc = mgr.createQueryContext();
XmlTransaction txn2 = mgr.createTransaction();
expr.execute(txn2, qc);
txn2.commit();
