[rules-users] top n - accumulate function parameters

[Evans, Jess]

I'm trying to average top N items.  I can of course collect the items
and do the rest in the consequence, but thought it might be a scenario
applicable to a custom accumulate function.  However, the accumulate
function interface methods only take one parameter.  If I were to
declare a function top(N, things) within an accumulate call would drools
autobox the parameters into some sort of collection?  
 
Maybe this is a naive solution anyway.  I am still learning to think
declaratively.
 
 
cheers,
