public interface TransactionalEvent

extends Event

TransactionalEvent reflects an event in a simple transaction. The lifecycle of a transaction (and therefore the sequence of related transactional events) is as follows:

  BEFORE_COMPLETION
  if (commit() is requested) {
    BEFORE_COMMIT
    COMMIT
    AFTER_COMMIT
  }
  if (abort() is requested) {
    BEFORE_ABORT
    ABORT
    AFTER_ABORT
  }
  AFTER_COMPLETION

Notes:

• Using composed events created as bitwise sum of one of the TransactionalEvent event types is allowed.
