    • Method Detail

      • lookup

        java.util.List<Mirror.Entry> lookup​(java.lang.String pattern)
        Obtain all the services matching a given pattern. The pattern is matched against all service names in the local mirror repository. A service name may contain '/' as a separator token. A pattern may contain '*' to match anything up to the next '/' (or the end of the name). This means that the pattern 'foo/*/baz' would match the service names 'foo/bar/baz' and 'foo/xyz/baz'. The pattern 'foo/b*' would match 'foo/bar', but neither 'foo/xyz' nor 'foo/bar/baz'. The pattern 'a*b' will never match anything. As a special case, a pattern can end in '**' to match the rest of a name including '/' separators.
        Parameters:
        pattern - The pattern used for matching
        Returns:
        a list of all matching services, with corresponding connect specs

      • updates

        int updates()
        Obtain the number of updates seen by this mirror. The value may wrap, but will never become 0 again. This can be used for name lookup optimization, because the results returned by lookup() will never change unless this number also changes.
        Returns:
        number of slobrok updates seen
