There are (at least) two ways of doing this. Both rely on a Java thread which will call a method at some given time. Such a class for handling timeouts is not difficult to write, although handling a large number of simultaneously running timeouts efficiently requires a little circumspection.
Now, given that you can have an object's method being called at a given time, you can either write your rules depending on a fact Time with the current time that is inserted as a result of a timeout expiry, with another fact containing the required time. For a periodic task depending just on the hour of the day this would probably preferable. The other way would be based on an additional flag in your facts, initialized to false and updated to true by a Timeout action, with the rule's firing depending on this flag being true. -W On Thu, Feb 11, 2010 at 5:55 AM, Yasir Khalid <y.k.tha...@gmail.com> wrote: > Hai There, > I am curious about a rule that the pattern (LHS) is depended on timing > event, what i meant the rule fired on specific time. > for example, a dummy and small program that should able to print out "Good > Morning" for every 8'Clock morning , > > I have tried to google and see on the manual, i just could not find any idea > on how to do it. > Thanks > > -- > - Yasir - > -------------------------------------------------------------------- To unsubscribe, send the words 'unsubscribe jess-users y...@address.com' in the BODY of a message to majord...@sandia.gov, NOT to the list (use your own address!)
