missing value

missing value

---

Description

This is actually a class, but it has no values; all you'll ever see is the class itself, so it works as if it were a constant. It seems to be a way for an application to return a value while signaling a nonvalue; it isn't an error, and it isn't a failure to return any value at all.

Example

 tell application "Finder" to get description of folder 1 -- missing value
