java.lang.Objectorg.apache.sshd.common.util.SelectorUtils
public final class SelectorUtils
This is a utility class used by selectors and DirectoryScanner. The functionality more properly belongs just to selectors, but unfortunately DirectoryScanner exposed these as protected methods. Thus we have to support any subclasses of DirectoryScanner that may access these methods.
This is a Singleton.
