[rules-users] firing explicit rules or agend-groups

[Chris Richmond]

I completely agree with everything you said and I feel I should be trying to
do things in that manner myself.hence, my hesitence to create static java
classes/methods for use as function libraries and rely instead on defined
functions in the rule if possible(from an earlier discussion).

 

I have been reading on the ruleflow recently and discovered that I in fact,
may need to be using some fo those features isntead of a fusion-centric
approach I was taking before, since I have some processes that need to be
fired off during rule execution and take time to complete.   Can fusion and
ruleflow be used seamlessly together..or more specifically are there samples
containing the melding of two.  I am essentialy dealing with periodic sensor
data incoming(hence my decicion to examine fusion as the solution ) but have
since realized that there is a worklfow or process that needs to be kicked
off and follow up processes that need to be completed in order to make
further decisions on the objects in working memory(which ruleflow sounds
ideal for).  

 

Also, are the bug fixes available in binary download or only in src?  I have
had a hell of a time getting maven to work for me.

 

Thanks very much,


Chris

   Sorry for the short answer... busy day.

   The main problem with agenda filter is that it is defined in application
code and so creates a dependency in the rules from the application code. So,
you break one of the biggest advantages of rules that is to have a separate
lifecycle for rules. There are other small things too, but that is IMO the
most limiting. I use agenda filters only for unit testing and debugging.

   My preferred approach is to model the rules in a way that they only fire
when they should fire, using ruleflow, agenda-groups and other "rule
features" as opposed to have the application messing with the agenda.

Ok.well when the recognized expert says something is not their preferred
approach, it begs the question .what is your preferred approach for handling
this?

 

Thanks,


Chris

   Chris,

   Although not my preferred approach, you can use agenda filters as a
parameter to fireAllRules().

Hello,

 

I thought I had encountered a sample of performing a:

 

session.fireAllRules();

 

except on explicit rules or at least on a specific agenda group.but I cannot
seem to locate that in the API for sessions..did I miss something or did I
imagine something before?

 

 

Thanks,

Chris
