Where ec is our SharedEditingContext. Is that the correct usage?
Well you only want to do this when there's a need to refresh the data
in the shared ec. The two scenarios are:
- upon application launch
- when you've inserted/saved some new objects (via a non-shared ec)
that need to be shared.
Objects that are already known by the sharedEC (if deleted/updated)
will automatically be picked up by the sharedEc via notifications.
So the general usage other than that is...
- sharedEC.objectsByEntityName()
- sharedEC.objectsByEntityNameAndFetchSpecificationName()
...depending on which method you used to fetch the objects into the
sharedEC and/or your particular usage.
Is it safe to assume that if the SharedEditingContext does not
contain the
data it will retrieve it. And if it does contain the data that it
will use
it instead of re-fetching from the DB?
No. See above...
What is the purpose of the "Share all objects" checkboxes in the
EOEntity in
EOModeler? Is it related to the "Cache objects" check box? Does EOF
fetch
these things into the SharedEditingContext automatically?
We have a bunch of data that is static (lookup codes, etc) that are
used in
relationships to other EOs that are not static. Can we fetch the
lookupCodes
into the SharedEditingContext and make use of them in the regular
editing
contexts?
localEC.setSharedEditingContext(null);
EOUtilities.localInstancesOfObjects(sharedEC, "Entity");
// i.e., do not make changes to shared objects (and their relatives)
// without doing so in a non-shared EC.
Thanks again for all of your help. Hopefully other people have
learned as
much as we have.
It's certainly helpful to understand the ins/outs in more detail...
