Re: [rules-users] Firing the rule at the basis of time

For a small number of facts representing future actions a rule with a timer would provide a generic solution. But timers have static literal durations, which means that you need to let it fire repeatedly, and test its due-time in the consequence. (You could devise more efficient but also more elaborate ways involving more than one checking rule with increasing granularities.) However, I think that using a simple (Java) timer that inserts an "IsDue" fact for each timed fact whenever its due-time arrives would also be a good solution. And if you need to handle a large number, data structures such as a Binary Heap Queue provide a good way of managing the queue of all future actions. -W On 5 May 2011 23:16, kkelleyjr <karl.kelley.jr(a)gmail.com&gt; wrote:
