Hi, I've been writing my own userfunctions in Java for Jess and have
managed fine returning strings, integers and doubles to Jess but now I
want to return an array but have come stuck and don't know the
syntax well
enough to know how to do it. Error = "The constructor Value(String
[], int)
is undefined". Once I pass back my Java array of type String to my
Jess
code I will be hoping to iterate through it. Thanks.
------------------------------------------------
public Value call(ValueVector vv, Context c) throws JessException {
String s = vv.get(1).stringValue(c);
int i = vv.get(2).intValue(c);
String list[] = splitMessage(s, i);
return new Value(list, RU.LIST);
}
In Jess 7, one easy way to turn any kind of array into a ValueVector
is to use the static "objectToValue()" method in the jess.RU class.
return RU.objectToValue(String[].class, list);
This will return a Value of type RU.LIST containing a ValueVector of
RU.STRING objects.
in Jess 6, you have to do it yourself;
ValueVector vv = new ValueVector();
for (String s: list)
vv.arg(s);
return new Value(vv, RU.LIST);
