Google Apps Script SpreadsheetApp Banding Class - How to access these methods - google-apps-script

Question

I am trying to figure out how to access the Banding Class of methods for the SpreadsheetApp. This is not how to simply apply banding. Instead, I am trying to get the data related to a sheet that banding has been applied to.
Here is the Developers Documentation:
https://developers.google.com/apps-script/reference/spreadsheet/banding
I can use .getBandings() but this simply confirms whether or not a banding exits in the sheet. There is no data as to the details of that banding. For example, I would like to return the range of the banding.
I also learned that when a banding is applied, the background color of the cell stays default, so I cannot utilize those methods to determine the details.
Here is the link to a Sheet with banding applied. I have added a few lines of script to show what getBandings() returns. Feel free to make a copy.
https://docs.google.com/spreadsheets/d/1xRuwE8moueSY5ZizZcy6KPkVmhJmOITN9Bql7XgHY3g/edit#gid=0
Any advice on how to access/utilize the methods in the Banding class would be appreciated.
From a comment to an answer
I am trying figure out the list of methods that would open up that class in SpreadsheetApp. I have experimented with SpreadsheetApp, getActiveSheet, getSheetByName, getRange and more. I cannot figure out how to open up that set of commands in the Banding class.

Answer 1

For example, I would like to return the range of the banding.
To get the range of a banding use the getRange() method of Class Banding
getBandings() returns an interable object. Below is a simple example of how to get the address of the range of a banding. It assumes that the spreadsheet has at least one banding.
function myFunction(){
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var bandings = spreasheet.getBandings();
var range = bandings[0].getRange();
Logger.log(range.getA1Notation());
}
