One way could be:


when

 

      Fire($room : room)

      $sprinkler : Sprinkler(room contains $room)

      Room (this == $room, someField == "SomeValue")

      then

            modify($sprinkler){

                  setStatus(true)

                  };

End


If you dont have the Room as a Fact Type, then:

when

 

      Fire($room : room)

      $sprinkler : Sprinkler(room contains $room)

      Room (someField == "SomeValue")from $room

      then

            modify($sprinkler){

                  setStatus(true)

                  };

End


I'm not 100% sure about this, but at least you can start from here

Hi,

 

Is there any way I can represent an array of values in my rules??

I want to do this:

Fire{

Room,

Status}

Sprinkler{

Object [] Room = new Room[]{new Room(),new room()}

Status

}

Room{

Name,

Number}

 

Rule “ if fire in room start sprinkler if room has sprinkler”

No-loop true

when

 

      Fire($room : room)

      $sprinkler : Sprinkler( room == $room) # how can I search through the array of room values here???????

      then

            modify($sprinkler){

                  setStatus(true)

                  };

End

 

 

Any Idea if that is possible to implement in rules???

I could do it with adding different instances of sprinkler and rooms. But I want to minimize the amount of repetition in data stored and loaded into the working memory.

 

Any idea??

Thank you,

M
