[Rd] Reference Classes: shortcut like 'isS4' for Ref Classes?

Dear list,

is there a shortcut-function to check whether a class is a Reference Class or not? There's something like this for S4 classes ('isS4(object)'), but I couldn't find anything regarding Ref Classes.

Currently, I'm doing it this way, which is a bit clumsy:

A <- setRefClass("A", fields=list(X="numeric")) a <- A$new()

isRefClass <- function(object, ...){

     return(getClass(class(object))@class == "refClassRepresentation") # getRefClass(class(object))@class == "refObjectGenerator" }

[1] TRUE Regards,
