@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.
