Refresh resource after external alteration to file [message #328487]

Hi,

I have code that has to save via a path (String). So, I create my own
FileOutputStream that writes the file to the workspace (not via IFile),
and close the stream. The workspace is obviously not aware of this, and
I need to hit refresh before using the file (I use a CommonNavigator).
Is there some way I can locate the file in the workspace by name or
external (non-workspace) path, so I can get a handle to the IFile and
call "refresh" programmatically? Or could someone recommend another
strategy so that the resource is refreshed automatically on external
modification?

Cheers,

.../Ola

Use IWorkspaceRoot.getFileForLocation() to get the IFile and do a
refreshLocal() on that.

The simplest for you would be to use file buffers. You can get it by
path and it will even handle the load and save operations for you.

getting IFile given File:

final IWorkspace ws = ResourcesPlugin.getWorkspace();
final IWorkspaceRoot wsroot = ws.getRoot();
final IPath path = new Path( f.getAbsolutePath() );

final IFile[] wsFiles = wsroot.findFilesForLocation( path );

if( wsFiles.length > 0 )
{
return wsFiles[ 0 ];
}

return null;
}
