Hi,<br><br>I have two questions.<br><br>1) Is there any other way/method in Drools to test the truth value of a condition other than "eval"? <br>In almost all rules of my application needs to test conditions, and it takes ages to run using "eval". <br>
<br>2) Say I have a java method which returns a boolean, and I have used it within an "eval" function. (eg: eval(message.emptyMessageFinder()) )<br>This "emptyMessageFinder()" method will return a "boolean" if there's an empty message. This function is containing many loops and recursive operations.<br>
<br>Will I get a performance improvement if I alternate the above such that the "emptyMessageFinder()" method sets a boolean attribute (anyEmptyMessage)<br>in the Message class to true and false, and I'm using following in my drl.<br>
<br>when <br> m: Message()<br> m.emptyMessageFinder()<br> eval(m.anyEmptyMessage) //can I use eval here??<br>......<br><br>If someone can answer these questions it would be a great help!<br><br>Thank you in advance!<br>
