```{index} single: SelectSaver ``` # SelectSaver save and restore selected file handle ## SYNOPSIS ```perl use SelectSaver; { my $saver = SelectSaver->new(FILEHANDLE); # FILEHANDLE is selected } ## previous handle is selected { my $saver = SelectSaver->new; # new handle may be selected, or not } ## previous handle is selected ``` ## DESCRIPTION A `SelectSaver` object contains a reference to the file handle that was selected when it was created. If its `new` method gets an extra parameter, then that parameter is selected; otherwise, the selected file handle remains unchanged. When a `SelectSaver` is destroyed, it re-selects the file handle that was selected when it was created.
