Re: [rules-users] Can I do a Collection contains Collection?
The line
Set() from RefData.getConstantValues()
seems to imply that ConstantValues is a Collection<Set<?>>, but this
seems strange.
Assuming that ConstantValues is a plain Set<?>, the rule might be written as
rule "ex1"
when
Example( $zips : zips )
$zip : ZipCode() from $zips
RefData( constantValues not contains $zip )
then
error()
end
or as
rule "ex2"
when
Example( $zips : zips )
RefData( eval( ! constantValues.containsAll( $zips ) ) )
then
error()
end
which might be faster.

zips below is a collection, i want to verify that each zip is in $e1.
rule "example"
when
e1: Set() from RefData.getConstantValues()
e2: Example( zips not in $e1)
