Re: [rules-users] Initial rule delay

In 5.4 timers support expressions for values. You can thus use a fact used to hold timer values (init and delay). This fact is created with some non-zero values, and reset all to zero once a first rule has triggered rule "delayAtFirstTime" timer(expr: $timerSpec.getDelay()+"s" , "0s") when $timerSpec : TimerSpec() .... then .... $timerSpec.setDelay(0); update($timerSpec); end Another solution is to create a fact that enable rule triggering that you insert "later" (may be that's the problematic aspect ...), something like that rule "DoSomethingWhenYouCan" when exists( OkToGo() ) .... then ... end Note that the OkToGo() fact can be inserted by a rule too ... rule "OkToGoAfter10s" timer(10s 0) when not( OkToGo() ) then insert( new OkToGo() ); end ----- Original Message ----- From: "Paul R." <reverselogic(a)gmail.com&gt; To: "Rules Users List" <rules-users(a)lists.jboss.org&gt; Sent: Mercredi 6 Juin 2012 16:47:03 Subject: [rules-users] Initial rule delay Hi, I'm looking for a way to delay a rules initial execution? In the following example, I would like to prevent the rule from firing when the first "Foo" event is inserted into the working memory. rule "DelayTest" when $n : Number() from accumulate( $f : Foo() over window:time(10s) count($f) ) then // bla end The timer attribute seems to almost support what I'm looking for, i.e. it allows for an initial-delay to be specified; but if the repeat interval is omitted, it uses the initial delay as the repeat interval. timer ( int: <initial delay> <repeat interval>? ) In my case I would like to block the execution of the rule for an "initial-delay" period, but after that time has elapsed the rule should fire when every time a new "Foo" event is inserted into the working memory. What is the recommended way to do this?
