                                  throws InvalidPatternException
        Create path matcher
        Parameters:
        pattern - a pattern
        pathSeparator - if this parameter isn't null then this character will not match at wildcards(* and ? are wildcards).
        dirOnly - a boolean.

        never null
        Throws:
        InvalidPatternException

        Matches entire given string
        Parameters:
        path - string which is not null, but might be empty
        assumeDirectory - true to assume this path as directory (even if it doesn't end with a slash)
        pathMatch - true if the match is for the full path: prefix-only matches are not allowed
        Returns:
        true if this matcher pattern matches given string
