5.23日 师兄ttcn程序里DiagrmEditor.java里的程序 save部分的理解

public void doSave(IProgressMonitor monitor) {
// TODO Auto-generated method stub

performSave(monitor,
getEditorInput());
           
getCommandStack().markSaveLocation();

}

public void doSaveAs() {
// TODO Auto-generated method
stub

Shell shell =
getSite().getShell();
         final IEditorInput
input = getEditorInput();

SaveAsDialog dialog = new
SaveAsDialog(shell);
