```
public boolean okToCancel()
```
    See if it is ok to cancel. It is okay to cancel if the transaction is not cleaning up from an error. The assumption is that if the cleanUpOnError is/has been invoked, then there is no reason for the cancel to be processed as the transaction is going to end (ab)normally.
    
    Returns:
    
    true if it is okay to cancel.
  - okToCleanup
```
private boolean okToCleanup()
```
    See if it is ok to cleanup. It is okay to cleanup if the transaction is not cancelling. The assumption is that if the cancel is/has been invoked, then there is no reason to try to mark the transaction as being in error. The transaction will be cancelled in any case.
    
    Returns:
    
    true if it is okay to cleanup.
