Re: [dali-dev] quickly getting a list of Entites
|
Hi Neil,
Returning to this hijacked thread :)
While I'm sure there is some delay associated with initializing the Dali
plugins, this appears to be separate from that. I have about 10
projects in my workspace, and once my workspace is open, if I go to each
one and call:
JpaModelManager.instance().getFilledJpaProject(project)
there is a noticeable delay that averages about 10 seconds the first
time I call this method on each project. Even if there are no entities
in the project, it still takes 5-7 seconds.
The Dali team may not run into this as much, since in my case we are
calling this method outside of the Java editor from an external wizard;
so it may be a different code path. But the delay can be pretty
noticeable to the user in our wizard case. It doesn't really seem to be
an issue of "priming" the plugins; I'm wondering if when this method is
called outside of the editor, performance could be improved if perhaps
some notifications could not be sent (such as any property view events,
etc, since they would not be applicable).
I'm sure performance isn't the highest priority right now, but this may
be one area that can be looked at at at some point.
All this said, returning to the subject line, I'm assuming that
getFilledJpaProject() would still be considered the best way to retrieve
the entities in the project?
Thanks
Tom

Re: [dali-dev] quickly getting a list of Entites
Hi Tom,
We are wondering if the delay on your first access is related to our
plugins being (lazily) loaded, in addition to filling the model. What
type of delay are you seeing with your first query for the entities?
I'm hoping that a model fill for 3 entities would be pretty quick, but
if it also requires plug-in initialization, that could be the cause of
the delay. You might need to prime the plugins at an earlier point to
get a better response in your UI, but this is just a theory.
