Abstract

The invention is directed towards methods and apparatuses for archiving and unarchiving objects. Some embodiments of the invention archive and unarchive objects that have global and user settings in multi-user environments. To archive objects, these embodiments identify which object settings are global settings and which settings are user settings. They store the global settings in an archive, and then store the user settings in another archive. To unarchive each object, some embodiments identify the object'"'"'s settings in one or both archives. These embodiments instantiate the object, and retrieve its settings from the data archives and use the retrieved settings to define the values of the settings of the instantiated object. Some embodiments use key-value coding techniques to retrieve values and load values in an object. Key-value coding allows an archiving or unarchiving process to retrieve and load setting values for an object by using the setting names.

Claims

1. A method of storing a document, the method comprising:

receiving a command to save a particular multi-user document comprising data that is editable by a plurality of users in a multi-user environment, said particular multi-user document associated with an instantiated software object comprising shared settings that are defined uniformly for the plurality of users and user settings that are defined for a particular user in the plurality of users;

identifying, in response to the command, the shared and user settings of the instantiated software object that is associated with the particular multi-user document;

retrieving the shared and user settings of the instantiated software object;

identifying one or more non-default settings of the shared and user settings;

storing each non-default shared setting of the instantiated software object in a shared first data store; and

storing each non-default user setting of the instantiated software object in a user second data store that is different from said shared first data store.

2. The method of claim 1 further comprising:

identifying relationship information of the instantiated software object, the relationship information referencing another instantiated object in a set of instantiated objects; and

storing the relationship information in one of the shared first and user second data stores.

3. The method of claim 2, wherein the instantiated software object further comprises a name and value pair associated with the relationship information, wherein identifying the relationship information comprises retrieving the value from the instantiated software object based on the name.

4. The method of claim 1, wherein the instantiated software object further comprises a method that determines whether particular shared and user settings of the instantiated software object are non-default settings, wherein identifying the non-default settings of the instantiated software object comprises invoking said method.

5. The method of claim 2 further comprising using the relationship information to recursively identify each remaining instantiated object in the set instantiated objects.

6. The method of claim 2 further comprising using the relationship information to iteratively identify each remaining instantiated object in the set of instantiated objects.

7. The method of claim 3, wherein identifying the relationship information comprises retrieving the name from an auxiliary data store.

8. The method of claim 1, wherein identifying the shared settings of the instantiated software object comprises identifying the at least one related object.

9. The method of claim 1, wherein the shared settings are global settings.

10. The method of claim 1 further comprising receiving user input to edit the particular multi-user document prior to storing the one or more non-default shared and user settings.

11. The method of claim 1, wherein the shared first data store is a global archive that stores a plurality of global setting values.

12. The method of claim 1, wherein at least one of said shared first and user second data stores is stored in one of a text-based format and a binary format.

13. The method of claim 1, wherein the multi-user document is for editing with an application program.

14. A non-transitory computer readable medium storing a computer program that is executable by at least one processor, the computer program comprising sets of instructions for:

receiving a command to save a particular multi-user document comprising data that is editable by a plurality of users in a multi-user environment, said particular multi-user document associated with an instantiated software object comprising shared settings that are defined uniformly for the plurality of users and user settings that are defined for a particular user in the plurality of users;

identifying, in response to the command, the shared and user settings of the instantiated software object that is associated with the particular multi-user document;

retrieving the shared and user settings of the instantiated software object;

identifying one or more non-default settings of the shared and user settings;

storing each non-default shared setting of the instantiated software object in a shared first data store; and

storing each non-default user setting of the instantiated software object in a user second data store that is different from said shared first data store.

15. The non-transitory computer readable medium of claim 14, wherein the shared first data store is a first data file that stores the settings shared amongst the plurality of users, wherein the user second data store is a second data file that is separate from the first data file and stores the settings for the particular user.

16. The non-transitory computer readable medium of claim 14, wherein the computer program further comprises sets of instructions for:

identifying a relationship information from the instantiated software object, the relationship information referencing at least one other instantiated object associated with the particular multi-user document;

retrieving the relationship information from the instantiated software object;

determining whether the relationship information relates to a global relationship or a user relationship;

storing the relationship information in the shared first data store when the relationship information relates to the global relationship; and

storing the relationship information in the user second data store when the relationship information relates to the user relationship.
