reObject: Creates proper extended Object from a list obtained by unObject

Description

Rebuilds an object to its original class from a list which was usually obtained using unObject. The original class is deduced using the Class. value and its S3 constructor will be called using all other values as properties.

Usage

reObject(o, showStructure = 0)

Arguments

o

The list attempted to convert to its original Object.

showStructure

Flag to show/debug the conversion course. It can be 1, 2 or 0.

Value

Object of original class given by x$Class.

Warning

It could take some seconds for large and/or complex objects.

Details

The original class (x$Class. value) is called without any parameter, then all properties (names) in the list are set using assign. The procedure is recursive called if an object of class list is found inside x. If the original object was extended from Object, this object have to be already defined using S3 methodology, otherwise an error would occur.

Examples

# NOT RUN {
library(R.oo)  # needed library
o <- Object()
o$x = 1
o$y = 2
o$x
o$y
o
class(o)
names(o)
uo <- unObject(o)
uo
x <- reObject(uo)
class(x)
names(x)
x$x
x$y



### saving/retriving
library(R.oo)
o <- Object()
o$x = 1
o$y = 2
uo <- unObject(o)
uoTempFile <- file.path(tempdir(), "uo.Rdata")
save(uo, file=uoTempFile)
### perhaps other session here
library(R.oo) 
#if your object requiere other sub-class (extend Object) and/or method definition, 
#load it here before using reObject otherwise an error would occur.
load(uoTempFile) 
class(uo)             ## uo now is a list
uo
x <- reObject(uo)
class(x)                ### now x is Object
names(x)
x$x
x$y
x
# }
