link.getAction?

I'm trying to copy all the links from an older edition of a document to a new document using javascript. How can I get the action of an existing link? In the Acrobat DC SDK Documentation, I see the link.setAction method but not link.getAction.

The idea is to align the pages of the older edition to the newer edition as much as possible and then copy the links from the older edition to the newer. (As such, replacing pages is not a viable solution.)

Thanks in advance.
