[rules-dev] Performance Question

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
