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,

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...

Hi Ed and thanks ...

in the meantime I did actually create a simple treeview with a basic with



viewer.setLabelProvider(new WorkbenchLabelProvider());

viewer.setContentProvider(new BaseWorkbenchContentProvider());



so I get back my tree for free (no icon no anything but it's a starting
point) and items are only loaded when I do expand the folder.



The trouble is ... what shall I do to be able to open an editor on the item
....

this was free when a linked the "dbfilesystem" to the resource view ...



What shall I do now?



I have tried using what follows



IEditorDescriptor desc2 =
PlatformUI.getWorkbench().getEditorRegistry().getDefaultEdit or(fileStore.getName());

try

{

page.openEditor(new FileStoreEditorInput(fileStore), desc2.getId());

}

catch (PartInitException e)

{

// TODO Auto-generated catch block

e.printStackTrace();

}



but I don't get anything ...

can u point me in the right direction or what is the class of the navigator
view so I could probably check what does it do (bear in mind that I know
very little of EFS and I haven't done any cache of the db file locally, but
just implemented the get input/output stream on the filestore)



thanks

Kar

Kar,

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

viewer.setInput(EFS.getFileSystem("eom").getStore(new Path("/")));

and on the double click on the tree item i'm just opening the editor with
....

IDE.openEditorOnFileStore(page, fileStore);

i did actually discovered that the problem is different ...
i cannot open only xml file ... follows the exception ....

The weird thing is that ... if I do open the file from the mounted EFS (from
resource view) - it works fine ...

or at least I can able to open the file using the xml editor (but when I
save it the document goes in out of sync ... but it has been saved correctly
.... just pressing F5 I get the editor back ...)



this whole thing is driving me crazy ...

hope u can help me



Thanks

Kar

In that case it's using an IFile and for sure the editor supports that.<br>

this whole thing is driving me crazy ...

Kar,

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

can u point me in the right direction or what is the class of the

very little of EFS and I haven't done any cache of the db file locally,
but
just implemented the get input/output stream on the filestore)

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).

catch (PartInitException e)

{

// TODO Auto-generated catch block

e.printStackTrace();

}



but I don't get anything ...

can u point me in the right direction or what is the class of the
navigator
view so I could probably check what does it do (bear in mind that I know
very little of EFS and I haven't done any cache of the db file locally,
but
just implemented the get input/output stream on the filestore)



thanks

Kar

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...

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

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

Kar
