Hey guys,

I need to use org.eclipse.ui.texteditor.IDocumentProvider in my plug-in. I looked into the interface and its implementations and I found the connect(object) method is not synchronized. Is it thread safe?

Thanks.

Raymond

Almost all types in *.ui.* packages are supposed to run in the UI thread
and hence not explicitly made thread-safe.

Thanks Dani. In the org.eclipse.ui.editors.text.TextFileDocumentProvider#connect() method. I saw it accounted the number of how many clients were connected by doing ++ info.fCount. But I could not think of any case that can make the connected clients to be more than one. Can you give me an example? Thanks.

e.g. open more than one editor on the same file.

I tried that but it always jumped to the opened editor. How can open multiple editors on one file?
