This is straightforward: You use $param, as usual, in the code snippet, and the list in the cell below:
Data coverType in ( $param ) "A","B", "C", "D" "X","Y","Z" To obtain the actual value from the fact, use a binding variable and refer to this in the action. Data $ct: coverType in ( $param ) -------------------- result add( $ct ) and an 'x' in the cells below, where required. -W 2011/2/5 David Smith <[email protected]> > Hi, > > I am pocing/learning drools and I am trying to implements Compound Value > Restrictions using 'In' in a decision table. > > I can do this in a rule like > > rule "CoverType Example" > when > $risk : Data( coverType in ("A","B", "C", "D")) > then > result.add("CoverType was one of A, B C or D"); > end > > I can also implement this in a decision table in a long winded fashion > Condition, Action > Data, result > coverType, add("$param") > A, CoverType was one of A, B C or D > B, CoverType was one of A, B C or D > C, CoverType was one of A, B C or D > D, CoverType was one of A, B C or D > > Is there a compact way to do this using a Compound Value Restriction using > in? > Something like: > > Condition, Action > Data, result > coverType in, add("$param") > "A,B,C,D", CoverType was one of A, B C or D > > What goes in the script part "coverType in"? > > The number of items in the list can be variable, so don't want to write > something that has $1, $2, $3, $4 > > Thanks > David > > _______________________________________________ > rules-users mailing list > [email protected] > https://lists.jboss.org/mailman/listinfo/rules-users > >
