Detailed Description

Specification to enable chunkwise execution of a process.

Interface enabling separation of the control of execution of any process from what actually is going on. The work is done by calling the doStep() method until either ErrorOccurred or Finished is returned. To enable logging and/or communication with the user, two types of info can be made available (the methods will be called before the step is executed). Firstly, a message. Secondly, info on the progress. It is common that Executors are combined to a new Executor object. This is the most common reason why totalNr() can change.

If doStep returns -1 (Failure) the error message should be in uiMessage().

The execute() utility executes the process while logging uiMessage() etc. to a stream. Useful in batch situations.

Return values

MoreToDo()	Not finished. Call me again.
Finished()	Nothing more to do.
ErrorOccurred()	Something went wrong.

Note: if function returns a value greater than cMoreToDo(), it should be interpreted as cMoreToDo().
