| * A listener that can be implemented to handle transaction related events. The methods on |
| * <code>TransactionListener</code> are invoked synchronously after the operation, commit or |
| * rollback, completes. The transaction that causes the listener to be called will no longer exist |
| * at the time the listener code executes. The thread that performed the transaction operation will |
| * not see that operation complete until the listener method completes its execution. |
| * |
| * <p> |
| * Multiple transactions, on the same cache, can cause concurrent invocation of |
| * <code>TransactionListener</code> methods. Any exceptions thrown by the listener are caught and |
| * logged. |
| * |
| * <p> |
| * Rollback and failed commit operations are local. |
| * |
| * <p> |
| * WARNING: To avoid risk of deadlock, do not invoke CacheFactory.getAnyInstance() from within any |
| * callback methods. Instead use TransactionEvent.getCache(). |
