BTP Issue 15 : Negative reply to BEGIN

Category: minor technical
Submitter: Gordon Hamilton, AppliedTheory
Page: 22
Question: Is there a negative reply to the BEGIN?

 There would seem to be two possible reasons why BEGIN didn't work:

 a)  the Factory has an internal problem - such as running out of resources

b)  the BEGIN has an associated CONTEXT, but the BT identified in the CONTEXT is not in an

appropriate state to enrol another Inferior.

 

The second can be treated as a FAULT(wrong-state) -  it's not strictly the state of the Factory that is the problem, so this will need a bit of modification of the explanation of WrongState (it will also mean the NOTE at the end of FAULT desicription will need changing.

 

Running out of resources would seem to be the same as any other transient (one hopes) failure of a  BTP component to do what it is asked - FAULT(General) would seem appopriarte.
