Question

I have a member which is a BitSet, and in a given rule, I’d like to test whether a particular bit is set, for example:

class Foo
{
  BitSet bar;
  // getter & setter
}

My rule that I would like:

rule "Test Bitset"
  when
    $f : Foo(bar ???) <-- what does this look like?
  then
    // do something
end

Is this possible?

Answer 1

According to the docs

Foo(bar.get(3))

would be a valid way to do it.
