是否可以在 Google Apps 脚本中迭代 ENUM？

Question

I would like to get all available Font-families in a Google Apps Script for Google Docs. FontFamilies are defined as FontFamily ENUM. Can I iterate over this ENUM to get all the possible FontFamilies in this document?

UPDATE: I have found my own answer:

var fontfamilies = DocumentApp.FontFamily.values();
for(var i in fontfamilies){
  Logger.log(fontfamilies[i]);
}

Answer 1

So to answer my own question (I guess to have it show as an answer I can't just edit my original question), Google Apps ENUM's do have a "values()" property / method just like in Java. It will give an array with the ENUM values, in this case the names of the font families defined in the FontFamily ENUM.

Here is an example code to iterate over these values:

var fontfamilies = DocumentApp.FontFamily.values();
for(var i in fontfamilies){
  Logger.log(fontfamilies[i]);
}

UPDATE april 2020: It seems that the FontFamily ENUM has been deprecated , and currently there is no way to retrieve an array of font family names for font families that are currently available to the document. I have opened an issue on the issue tracker , please star if you would appreciate this functionality.
