#gt?(other) ⇒ true | false

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns whether this topology version is potentially newer than another topology version.

Note that there is no total ordering of topology versions - given two topology versions, each may be “potentially newer” than the other one.

Parameters:

Returns:

  • (true | false) —

    Whether this topology version is potentially newer.
