NAME

SelectSaver - save and restore selected file handle

SYNOPSIS

    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.
