Instance Method Details

#<=>(other) ⇒ Object

First the positions are compared.

1 > 4 => true
2 > 3 => true

If those are equal the sets are compared.

-2 < -1

If the sets are also equal, an exception is thrown.

Sets are used for keeping links apart from comments, etc… Both links and comments etc. should be clustered and parsed from templates as clusters.
