Hi,
I've been trying to use the beanflow component to build a workflow, but
I seem not to be able to get it right. My goal is to use the beanflow
component to register a state (and then persist it into a database) and
to allow to do transitions between states (based on permissions granted
to the user, but this is another matter). So, so far I do not need my
workflow to change steps by itself since each change of state should be
triggered by an external event.
I took a look at the Javadoc, the source code and the examples, but I
did not understand where to put the business code. According to the doc,
I guess I'm supposed to write my own workflow, which subclasses the
class Workflow<T>, parametrizing it with an enum which holds the
different states my workflow can be in. Then the transitions between the
different states would be managed by additional methods I would write
myself.
Though:
- if my enum is <startStep, middleStep, endStep>, what use is there for
the methods startStep(), middleStep() and endStep()? Are they
automatically called by the introspector when the state of the workflow
changes?
- what is the difference between "return Step.myNextStep" and
"setNextStep(myNextStep)" ?
- could anyone provide me with a basic example which actually does
something like what I'm looking for, or even a hint to the solution?
Thanks in advance,
Florent Robineau
