Hello
I am trying to enhance my enhance my Rcpp class with the functionality to be
saved across R sessions. For convenience reasons I would like to do that in R,
using the ReferenceClass's S4 member function 'finalize()'. My plan is to
simply save all object's fields (vectors of various types) to a special list
(with a special class name), remove the Rcpp object, and save the plain R
object instead. Would that work/be a good option? In particular, what happens
on the C++ side if I call rm(reference_object)? Would that remove the C++ side
and free its memory? And how can the reverse be accomplished, that is, if an
object (identified by its class name) is loaded from a previous session,
rebuild the C++ side and form the original reference object?
Sort of finalising:
<art>
x = new( 'Rcpp_Myclass' )
x$finalize() calls:
x_list = make_my_special_list( x )
rm( x )
and then the system calls:
gc()
</art>
Sort of loading:
<art>
start_function_?() calls:
x_lists = look_if_there_is_some_x_lists()
for every x_list in x_lists:
name = name_of(x_list)
name = new( 'Rcpp_Myclass' )
name$assign_values_from_x_list()
</art>
Thank you for help.
