Hi
I am looking at versioning of objects. Objects comprise of valuetype
attributes, references to other objects and few set/unset methods.
Objects’s attributes can change in value. Once their value is changed,
this is a new version. I should be able to go back to last version (i.e.
restore the previous attribute value.) In case the attributes refers to
some other versioned object( and like that for n depth) I should be able
to restore.
set/unset are specifics, where restore means calling unset method.
What can be good strategies for implementing this.
regards,
rolo
