I would like to match on the class of a field. I know I can use "eval(option
instanceof OptionInstrument)", but my understanding is that the use of eval
precludes indexing. What I want is something like the below, which does not
work. Is some other mechanism other than putting type codes that are
redundant with the class for this use case?
thanks!
----
rule "Long Call/Put, Short Uncovered Call/Put"
when
position : Position(option : instrument, option.class ==
OptionInstrument.class)
then
...
end
