process parseInt method?

Hardware Arduino Yún
#1

In the gmail lamp blog I saw the process class seems to have a parseInt function.
I dont see this mentioned in the reference describing the class? Is this an undocumented feature?

If I do not expect an integer, how can I get the returned string with a similar function?

Process inherits from Stream, it's a Stream method

Oh thanks for the clarification!
