abstract Persist : unit -> string

Return Value

Type: String
The persistence string for the object that can be used to restore the same object later.

Remarks

The persistence string only contains enough information to restore the same object at a later time. It does not contain a copy of the data within the object. To retrieve the object using its persistence string, create a AFGlobalRestorer object and pass it the persistence string.
