Hi all, hope this is the right forum to ask questions about EFS .
I'm trying to build an example that with the EFS helps will make me build a
view with a representation of what is contained in my DB .
I did actually manage to do it but there is something that I don't not
really like .
When I start my test it starts to ask information about the whole tree - the
problem is that this operation can take a long time if the DB contains more
than a 1000 object ..
Is there a way to (for example) just read the information about the first
"folder" and only once it get expanded read it . I do understand that
eclipse must probably cache information about name and structure . but this
really make totally not usable .
Thanks
Kar

Kar,
This looks like the right way. How are you creating the file store
instance that you pass to the editor?

I'm not sure this is entirely avoidable. Eclipse does need to know the
time stamp for each resource the first time so that it can properly do a
refresh should the contents of the tree change outside the control of the

this need for an initial sync? I assume it's not actually loading files

Kar,
In that case it's using an IFile and for sure the editor supports that.

Kar,
This looks like the right way. How are you creating the file store
instance that you pass to the editor?

Kar,
I'm not sure this is entirely avoidable. Eclipse does need to know the
time stamp for each resource the first time so that it can properly do a
refresh should the contents of the tree change outside the control of the
IResource APIs. What specifically is driving the full walk. Is it indeed
this need for an initial sync? I assume it's not actually loading files
but just needs to understand the full folder structure. If that indeed is
taking an unusably long time, you probably need to rethink your design
where the user needs to take explicit actions to bring folders into
view...

Kar,
It kind of circles back to your original problem. To make it an IFile,
you need to use EFS as the backing for a view on your database. Maybe
ask the WTP newsgroup about support for different types of input (if
debugging the stack trace doesn't make that clear by inspection).

Kar,
This looks like the right way. How are you creating the file store
instance that you pass to the editor?

Kar,
I'm not sure this is entirely avoidable. Eclipse does need to know the
time stamp for each resource the first time so that it can properly do a
refresh should the contents of the tree change outside the control of the
IResource APIs. What specifically is driving the full walk. Is it indeed
this need for an initial sync? I assume it's not actually loading files
but just needs to understand the full folder structure. If that indeed is
taking an unusably long time, you probably need to rethink your design
where the user needs to take explicit actions to bring folders into
view...

Is there a way to (for example) just read the information about the first

Hi Ed and really thanks for all ur help ...
I guess at this point is better for me to stop ... at least since I will
fully understand what I can do to actually get an IFile from an EFS object
....
I could try to dig and solve the problem for a structure text editor but I'm
sure that the trouble will rise again once someone will use a different
plug-in inside the RCP application for editing any other kind of file .
I did have a look at the Workspace / Workspace root and a bunch of other
classes inside the Resources Plugin but it's a really mess ...
Still thanks for ur help
Ciao
