Btw, this brings me to a new syntax question for the default Drools rule
syntax. Is this possible:
when
m:Map()
eval( m.get("type") == "Point", $x : m.get("x") )
...
Circle( x == $x )
then
...
or, an alternative which may be clearer:
when
m:Map()
eval( m.get("type") == "Point" )
$x : m.get("x")
...
then
...
So, what I would like to have is:
1) looking at all Maps which have the value "Point" under the key
"type"
2) of all those Maps: store in a var what value they have under key "x"
3) reuse the var, here $x instead of having an expensive lookup over and
over again.
Is that possible? Or would I have to write my example above as
...
c:Circle()
eval(c.getX() == m.get("x"))
