Accumulate functions are very well documented in the Expert manual. Look for a section titled "Accumulate Functions".

You could also use accumulate with all the steps in inline code, which is documented in the preceding section.

Thanks for outlining the approach, Edson.

Unfortunately, I'm a newbie using drools, so I just need some clarification
on what you mean by 'matchAll is your own accumulate function with the
semantics you described.' ? Do you mean that I have to create a 'custom'
accumulate function ?

Edson, if that's the case, then I'll try to search for example of creating a
custom function. When I last searched, I did find an example on the
Internet, however, I don't think I found details of how to make the function
available to the rules engine (is it as simple as including the jar in the
classpath or do I need to take addtional steps to use Matchall in drl ?)

Can you please elaborate for the benefit of a noobie ?

Thanks
