Examples of com.arjuna.wst.Vote

com.arjuna.wst.Vote
When asked to prepare, a 2PC participant returns one of three types of vote: ReadOnly: does not need to be informed of the transaction outcome as no state updates were made. Prepared: it is prepared to commit or rollback depending on the final transaction outcome, and it has made sufficient state updates persistent to accomplish this. Aborted: the participant has aborted and the transaction should also attempt to do so. @see com.arjuna.wst.ReadOnly @see com.arjuna.wst.Prepared @see com.arjuna.wst.Aborted
