| @short implement a transaction manager to support non breakable interface methods |
| @descr Use it to support non breakable interface methods without using any thread |
| synchronization like e.g. mutex, rw-lock! |
| That protect your code against wrong calls at wrong time ... e.g. calls after disposing an object! |
| Use combination of EExceptionMode and ERejectReason to detect rejected requests |
| and react for it. You can enable automaticly throwing of exceptions too. |
