Rosetta Example: Object serialization

-
-

For details see http://rosettacode.org/wiki/Object_serialization

-
-
-
package req nx
-package req nx::serializer
-
-nx::Class create Being {
-  :property {alive:boolean true}
-}
-
-nx::Class create Animal -superclass Being {
-  :property name
-  :public method print {} {
-    puts "i am ${:name} alive ${:alive}"
-  }
-}
-
-

Demonstrating the behavior in a shell:

-

Create a few animals

-
-
-
% Animal new -name "Fido"
-% Animal new -name "Lupo"
-% Animal new -name "Kiki" -alive false
-

Print the created animals

-
-
-
% foreach i [Animal info instances] { $i print }
-

The loop prints:
- i am Kiki alive false
- i am Lupo alive true
- i am Fido alive true

-

Serialize the animals to a file

-
-
-
% set fpath [::nsf::tmpdir]/dump
-% set f [open $fpath w]
-% foreach i [Animal info instances] { puts $f [$i serialize] }
-% close $f
-

Destroy all animal instances:

-
-
-
% foreach i [Animal info instances] { $i destroy }
-% puts ===========
-

Print the existing animals (will print nothing)

-
-
-
% foreach i [Animal info instances] { $i print }
-% puts ===========
-

Load the animals again …

-
-
-
% source $fpath
-

and print it. The print output is the same as above

-
-
-
% foreach i [Animal info instances] { $i print }
