Code

public function matches(ConstraintInterface $provider) {

        foreach ($this->constraints as $constraint) {

            }
        }
        return false;
    }
    // when matching a conjunctive and a disjunctive multi constraint we have to iterate over the disjunctive one
    // otherwise we'd return true if different parts of the disjunctive constraint match the conjunctive one
    // which would lead to incorrect results, e.g. [>1 and <2] would match [<1 or >2] although they do not intersect
