React on Save [message #651662]

Hello,
I need a Listener on document changes. I know that there is a ResourceChangeListener or a builder for things like that.
The problem is, that my documents are no physical files in the workspace. Every document is loaded from a database. So the changes of a document are not recognized by those listeners and builders.
The question is, how can I solve this?

Maybe I can use a listener on the save event itself?

Thanks in advance & best regards
Alex

I'm not sure if the Save/Save All has been ported to the
Commands-Framework. If yes you could install a listener on the command.

It depends on which layer you need to know about 'save' and whether you
own that code (e.g. your own editor). The best approach would be to
write an EFS that backs your DB. That way Eclipse could handle your DB
document ike a 'file'.

Hello and first of all: Thanks for your answers!

I own the editor, its written with GEF and I have access to the code.
Could you please expleain EFS, I've never heard or read about a way to tell eclipse that there are files in a database...
I need just a way to indicate that a document has changed. No matter if its via Save-Event or ResourceListener and so on...

Thanks

Are now interested in the event that the document changed or do you have
to find out that it gets saved?

I have no idea of GEF but I guess it is extending the EditorPart and
hence you can overload the general save method. To check for dirty ness
you can consult the EditorPart#isDirty and for modifications you can
install a Listener on the EditorPart and listen if the dirty property
has been modified.

Then you could simply extend
org.eclipse.ui.part.EditorPart.doSave(IProgressMonitor).

Hi and thanks for your answers.

My description of the problem was not explained very properly.
I want to react on saves but outside of the plugin.
Which means I want a sort of a listener reacting to changes on my document in an external plugin

I know that I can overwirte the doSave Method in the Editor, but I need the implementation outside of the plugin as an "independent plugin"
