3 Autosave
|
Classes that implement this interface can be autosaved.
method
(send an-autosave:autosavable do-autosave) → void?
This method is called when the object is registered to be autosaved (see autosave:register).
procedure
(autosave:register obj) → void?
obj :
(and/c (is-a?/c autosave:autosavable<%>) (is-a?/c editor<%>))
Adds obj to the list of objects to be autosaved. When it is time
to autosave, the do-autosave method of the object is called. This
method is responsible for performing the autosave.
There is no need to de-register an object because the autosaver keeps a
weak reference
to the object; i.e., the autosaver does not keep an object
from garbage collection.
value
The path to the a table-of-contents file for the autosave files.
The parameter is inspected only when the autosave timer expires, which will not happen until
after the first call to autosave:register
value
The default value of the parameter autosave:current-toc-path, and the
path to the autosave that DrRacket uses.
procedure
Opens a GUI to ask the user about recovering any autosave files left around
from crashes and things.
This function doesn’t return until the user has finished restoring the autosave files. (It uses yield to handle events however.)
