Keep in mind that if/elsif/.../elsif implies a certain order for evaluating the conditions. Patterns in different rules are evaluated concurrently. The upshoot of this is that for a complete (i.e., with else) n-way if/elsif such as, e.g.,
if( c1 ) then a1 elsif( c2 ) then a2 else a3 the execution of a3 has the guard g3 = ( ! c1 && ! c2 ) the execution of a2 has the guard g2 = ( ! c1 && c2 ) the execution of a1 has the guard g1 = (c1) For any two of the guards gi != gj the following must hold gi && gj == false And for all guards g1,... gn you must have g1 || g2 || ... || gn == true -W On Wed, Dec 10, 2008 at 5:47 AM, hansari <[EMAIL PROTECTED]> wrote: > > I need rule for > > if (condtion1) > then (acton1) > if else (conditon2) > then (action2) > if else (condition3) > then (action3) > else (acton4) > > how can perform this by using defrule > please help me. > > thank you. > -- > View this message in context: > http://www.nabble.com/how-to-write-If-else-rule-tp20929177p20929177.html > Sent from the Jess mailing list archive at Nabble.com. > > > > -------------------------------------------------------------------- > To unsubscribe, send the words 'unsubscribe jess-users [EMAIL PROTECTED]' > in the BODY of a message to [EMAIL PROTECTED], NOT to the list > (use your own address!)
