Overview

Note:

this works with Hash object where basic keys are:

  • nodeId
  • name
  • parentId
  • archived
Note:

other properties can be part of the Hash although they may not influence the results.

Note:

that for special exposed methods question mark ? on a property of the model checks if that property changed (it has nothing to do with checking the boolean value of that property)

Differences between node before and after
