Archive if I am not : mistaken is the model of permanent storage. PT is the model of in-memory : storage. ... which is why PT is very complementary.
There are reasons that you might want to have it as an archive target. You get archives in JSON, INI, Registry formats for free, and even an alternative format for XML. I have actually implemented an Archive class that uses ptree, so it definitely is possible and quite easy also. I might post it in the future when I make it somewhat more general (it's just a quick hack now). Truth is, it is not very fast, but if you want a sample of archive in JSON, here you go: { "d": { "class_id_type": "1", "class_name_type": "class Derived", "tracking_type": "0", "version_type": "0", "Base": { "class_id_optional_type": "0", "tracking_type": "0", "version_type": "0", "b": "78" }, "d": "111" }, "d2": { "class_id_type": "1", "Base": { "b": "11" }, "d": "146" }, "b": { "class_id_type": "0", "b": "52" }, "i": "3", "v": { "class_id_optional_type": "2", "tracking_type": "0", "version_type": "0", "count": "5", "item": { "count": "3", "item": "1", "item": "2", "item": "3" }, "item": { "count": "0" }, "item": { "count": "0" }, "item": { "count": "0" }, "item": { "count": "0" } } } Kind regards, Marcin
