POHow to implement less and greater than rules with decision table in drools?
text
Body
copied!<p>I would like to implement simple rules based on the less and greater values in drools using decision table.</p> <p>It is easy enough to implement the rules in drl, for example:</p> <pre><code>rules "less than" when Example(value < 10) then System.out.println("Less than 10") end rules "equals" when Example(value = 10) then System.out.println("Equals 10") end rules "greater than" when Example(value > 10) then System.out.println("Greater than 10") end </code></pre> <p>But how can I translate it into decision table in drools? All the examples I have seen so far is to have the comparison done in condition cell. Is it even possible to do the comparison in value cell?</p> <p>All example I had seen are in format of:</p> <pre><code>CONDITION | ACTION Example | value | -----------------------------------|------------------------------------- 10 | System.out.println("equals to 10") </code></pre> <p>But that only applies to 1 rule, and doing the following totally has different meaning:</p> <pre><code>CONDITION | CONDITION | CONDITION | ACTION Example value | value > $1 | value < $1 | -----------+------------+------------+---------------- 10 | 10 | 10 | ??? </code></pre> <p>Is even possible to do the following?</p> <pre><code>CONDITION | ACTION Example | value | -----------------------------------+---------------------------------------- 10 | System.out.println("equals to 10") > 10 | System.out.println("greater than 10") < 10 | System.out.println("less than 10") </code></pre> <p>What is the right way to implement these rules?</p>
