What you need is called "inline eval expression" (see the Drools Expert
manual),
or an eval conditional element. The first one might be written as:
$c:Cheese(type == "chedar", eval( this.existsInShop("shopName") ) )

Hi All,
I'm trying to call a class method from the LHS of a rule in the following
way:
public class Cheese{
private string type;
//setters and getters
public boolean existsInShop(String shop){
...
return true;
}
}
I would like to call the method "existsInShop" from a rule:
Rule "Rule1"
when
$c:Cheese(type == "chedar", existsInShop "shopName")
then
System.out.println("Rule1 is fired");
end
I get the compilation error: "no viable alternative at input "shopName"
in
rule "Rule1" in pattern document". How can I call the method from the
rule?
Thanks in advance.
