property name

Load an additional attribute from the real object.

This should load self.$attrname and cache any data that might be useful for future load operations.

obj_make_compatible(primitive, target_version)

Make an object representation compatible with a target version.

This is responsible for taking the primitive representation of an object and making it suitable for the given target_version. This may mean converting the format of object attributes, removing attributes that have been added since the target version, etc. In general:

  • If a new version of an object adds a field, this routine should remove it for older versions.

  • If a new version changed or restricted the format of a field, this should convert it back to something a client knowing only of the older version will tolerate.

  • If an object that this object depends on is bumped, then this object should also take a version bump. Then, this routine should backlevel the dependent object (by calling its obj_make_compatible()) if the requested version of this object is older than the version where the new dependent object was added.

  • primitive – The result of obj_to_primitive()

  • target_version – The version string requested by the recipient of the object

Save the changed fields back to the store.

This is optional for subclasses, but is presented here in the base class for consistency among those that do.
