Hi,
Sorry about not posting the code. My mistake.
Classes :
public class Room {
private String name
private int number;
// getter and setter methods here
}
public classs Sprinkler {
private Room room;
private boolean on;
// getter and setter methods here
}
public class Fire {
private Room room;
// getter and setter methods here
}
I load 2 input files: 1. with data of fire and Room { f1, r1;f2, r2}
2. with data of sprinkler and Room {"n/a",r1,"n/a",r3}
I am writing rule " if fire exists in room start sprinkler" { so if f1 and r1
in this case: I should get s1, r1 } But since no sprinkler in r2 , That data
should not get outputted.
I want my ouput file to look like:
Name Number
Xyz 1
# xyz is my room name and 1 is the room number : r1(xyz,1) . But I am unable to
delete entries.Is there anyway I can do it?
#only this should appears as the other room does not have a sprinkler.
when
Fire($room : room)
$sprinkler : Sprinkler( room == $room, modified == false )
Then
$sprinkler.setmodified(true);
modify( $sprinkler ) { setSprinkle( "s1" ) };
end
Error:
I am getting the error at a place where I am trying to write back from my
working memory to my output file.
It is happening because the second rule to turn on the sprinkler does not work
and as a result a null value is getting stored.
Is it possible that there can exists 2 different Room() objects with the same
room.name ??
Because the room objects are getting stored from different files to the working
memory ??
Do you think it better to store room objects in a separate list??
I store all information into a list and load that into the memory.
Am I going wrong here?
Please help.
Thank you.
