Hello all,
This is the set of rules i have
rule "IP Route File rule"
salience 2000
when
Line ( line matches "^.*\s+show\s+ip\s+route\s*$" )
Line ( line matches "^.*\s+dest\s+address\s*$ )
file : FileFinder()
then
file.setFileType("ip route file");
drools.halt();
end
All I am doing in rules is, I read each line from the given file, convert
them into Line Objects and see if any of my
rules matches. There are about 50 such rules, that will help me
differentiate what kind of file is present in my input
directory.
The question I have , is there a way I can know if Line Object matched any
of the rules ? If a Line Object is not matched by
any of rules, I can just retract that object from the memory and prevent Out
of Memory Exception if the file size is huge
Thanks
Shiva

You could add an attribute on the Line object to mark it as processed or
something when a match is found. You could then write another rule that
looks for unprocessed lines and retracts them.

Are you sure you want to use rules for this? If you're not going to do analysis more
complex than what you've described I'd say straight java is a better option.
That being said, this is one thing to try:
1) Add a "processed" property of type boolean to Line, default value false.
2) Set processed = true on Lines that are matched
3) Have a low salience rule (lower than all other rules that match a Line) that matches a
Line with processed == false and retracts it. It must be low enough priority so it fires
after any other rules that could match the Line.

There is more to it ,but just to give an idea.
I thought about the idea you have given me, but just did not get an idea of
how to implement
Say in the below rules itself
rule "IP Route File rule"
salience 2000
when
Line ( line matches "^.*\s+show\s+ip\s+route\s*$" )
Line ( line matches "^.*\s+dest\s+address\s*$ )
file : FileFinder()
then
file.setFileType("ip route file");
drools.halt();
end
When I encounter a line "show ip route" in a file , I know that match
occured. But how do I implement it
Did you mean I should have written a separate rule like
when
Line ( line matches "^.*\s+show\s+ip\s+route\s*$" )
then
update (the above line with proceed==true )
In that case will not explode the number of rules (50 * say 3 matches)
Thanks

You only have to add one additional rule (the one that retracts unmatched Lines) but each
of your existing rules will have to modify each Line matched to set "processed =
true"
