Is there any way to check the class of an ALTREP?
Hi all,
I would like to determine if an ALTREP object is from my package, I see
there is a function `ALTREP_CLASS` defined in RInternal.h but its return
value is neither a `R_altrep_class_t` object nor an STRSXP representing a
class name. I do not know how to correctly use it. Any suggestions?
Thanks,
Jiefei

...y useful documents.
Actually, the question is related to the SharedObject package that Benjamin
has pointed to. I wanna
avoid sharing an object that has already been shared, so I need to check
whether an object is an ALTREP
that is defined in my package. Since the ALTREP definition involves an `
R_altrep_class_t` object and a
class name, I will expect to see a method defined in R to retrieve such
information. I hope this can clarify my question.
Best,
Jiefei
