BFMatcher and crossCheck

edit

Hi,

When I use BFMatcher I can find in constructor option crossCheck

Now if I want to use new method cv::DescriptorMatcher::create("BruteForce-Hamming") Is it possible to fix crossCheck to true?

my program is

descriptorMatcher = cv::DescriptorMatcher::create("BruteForce-Hamming");
if (descriptorMatcher.dynamicCast<cv::BFMatcher>()!=NULL)
{
    descriptorMatcher.dynamicCast<cv::BFMatcher>()->?????? // crossCheck = true
}

Thanks for your help
