Creation of IFIles to slow [message #325473]

Hey,

i am importing some files into the workspace and create the new IFiles
with the method attached below. But somehow the speed of the copy
process is to low compared to other copy operations but i somehow can
not figure out why this is the case.

I fear that the workbench adds up some time because of the "resource
state tracking" and workspace file creation through several calls of
IFolder.getFile(), but am not sure that its not my fault with using the
wrong way to create the files. Any help appreciated

greetings Philipp

private void copyFileToWorkspace(File source, IFile destination) {
FileInputStream fis = null;
BufferedInputStream bfis = null;
try {
fis = new FileInputStream(source);
bfis = new BufferedInputStream(fis,8192);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
if (!destination.exists()) {
try {
currentMonitor.subTask("Copying file:" + destination.getName());
destination.create(bfis, true, currentMonitor);
currentMonitor.worked(1);
} catch (CoreException e) {
e.printStackTrace();
} finally {
try {
bfis.close();
fis.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}

Have you tried debugging into the destination.create() call, to see if it is
doing anything unexpected?

I imagine there's a WorkspaceRunnable inside there, but if not you might
want to wrap your whole task inside one to defer update notifications till
the end. Just a thought, I'm a newbie to that code as well.

I haven't tried debugging it there will do it. Though as far as i
understood the mechanics wrapping the modifications in a
Workspacemodifyoperation should delay those updates already. And that is
what i do in the end. Using this method from a Subclass of
Workspacemodifyoperation.

thanks for your thought

I agree - sorry, hadn't realized that from your earlier post.

I'd try debugging into it to see if there are any surprises behind the
curtain.
