Subject [jira] Closed: (UIMA-331) Provide/extend a built-in flow controller that can be configured to do ParallellStep or to continue after error
Date Thu, 07 Jun 2007 19:23:25 GMT

     [ https://issues.apache.org/jira/browse/UIMA-331?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Adam Lally closed UIMA-331.
---------------------------

    Resolution: Fixed

Added the AdvancedFixedFlowController as example code.  It uses configuration parameters to
specify the flow.  If we want to enable a different way of doing this in the core, we can
do that later.

> Building on the infastructure implemented in UIMA-327, we should provide a built-in flow
controller that can be configured to return ParallelSteps and/or to continue after errors.
 There are a few options:
> 1) extend the existing <fixedFlow>.  This could be messy to do (in the Java API)
in a backwards compatible way
> 2) add a new kind of flow object, .e.g. <complexFlow>.  Also would need a corresponding
flow controller that interprets it (or possibly just modify FixedFlowController to handle
both <fixedFlow> and <complexFlow>)
> 3) do this entirely with configuration parameters in the FlowController.  This can be
done with the existing framework code (and wouldn't require CDE changes as 1 and 2 would).
 But it is more of a change from what the user is familiar with.  Still, flow controller configuration
parameters are a very general solution and if we think this is the way of the future maybe
we should go ahead and use them now.
