    NAME

    SelectSaver - save and restore selected file handle
     
    

    SYNOPSIS

        use SelectSaver;
    
    

        {
           my $saver = new SelectSaver(FILEHANDLE);
           # FILEHANDLE is selected
        }
        # previous handle is selected
    
    

        {
           my $saver = new SelectSaver;
           # 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.
