MatchFinder Initialization

Hello!

My name is Daniel.
I’m trying to initialize a object of MatchFinder Class. I use a MatchFinder object:
MatchFinder Finder;
Finder.addMatcher(…);
Finder.addMatcher(…);

After this, I want to delete the content of the MatchFinder object, and then I would add new matchers. How can I do it? I must use the same object, i cannot use a new object. Any idea?
Thank you!
