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

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.
