interface UpdaterInterface

Defines an interface for a class which can update a Drupal project.

An Updater currently serves the following purposes:

  • It can take a given directory, and determine if it can operate on it.
  • It can move the contents of that directory into the appropriate place on the system using FileTransfer classes.
  • It can return a list of "next steps" after an update or install.
  • In the future, it will most likely perform some of those steps as well.
