Question

If I have handle to file how do I create a document and write to it? Right now, I am having to delete the file completely and recreate with new content as shown below :

IFile file = getFile(); 
file.delete();
file.create(input, false, null);

EDIT : This is in an eclipse plugin, not a regular java program.

Found the answer here : http://old.nabble.com/how-to-get-the-IDocument-of-an-ITextFileBuffer-created-from-an-IFile–td19222160.html

Had to modify a little to suit my need:

FileEditorInput editorInput = new FileEditorInput(file);
IWorkbench wb = PlatformUI.getWorkbench();
IWorkbenchPage page = wb.getActiveWorkbenchWindow().getActivePage();
IEditorDescriptor desc = wb.getEditorRegistry().getDefaultEditor(file.getName());
IEditorPart editor = (IEditorPart)page.openEditor(editorInput, desc.getId());
ITextEditor textEditor = (ITextEditor) editor.getAdapter(ITextEditor.class);
IDocumentProvider documentProvider = textEditor.getDocumentProvider(); 
IDocument document = documentProvider.getDocument(editorInput);
document.replace(position, 0, content);
