Can you call a getter from a static function?

I am calling an instance of my boxes class (that draws boxes on the screen) from my document class. This class has a getter function that parses the array containing all the lines I have used to create the boxes. I can call that getter from my document class no trouble. But I have another PUBLIC STATIC class (call it my Dissolve class) that is required to dissolve these boxes from the screen. So I need to get the Array from the boxes class. I can’t seem to do it…

Here is the code for my getter function (Boxes Class):

public function get boxes():Array {
   return boxArr;
  }

Here is the code to get the Array from the document class where an instance of the boxes class has been created and called “box” I have turned it into a getter function to try and access it from the PUBLIC STATIC class Dissolve:

 public function get pbox():Array {
   tt = Array(box.boxes);
   return tt;
   trace("Got box from dboxesParser");
  }

And here finally is the DISSOLVE class I am trying to access it from:

package { 
 public class TraversePage {
  public static function st_bi():void {   
 
   var _tt:Array = Array(portfolio.pbox);
  }
