NAME

       IO::TieCombine - produce tied (and other) separate but combined variables

VERSION

       version 1.005

SYNOPSIS

       First, we set up a bunch of access points:

         my $hub = IO::TieCombine->new;

         my $str_ref  = $hub->scalar_ref('x');
         my $fh       = $hub->fh('x');
         my $callback = $hub->callback('x');

         tie my $scalar, $hub, 'x';
         tie local *STDOUT, $hub, 'x';

         tie local *STDERR, $hub, 'err';

       Then we write to things:

         $$str_ref .= 'And ';
         print $fh "now ";
         $callback->('for ');
         $scalar .= 'something ';
         print "completely ";
         warn "different.\n";

       And then:

         $hub->combined_contents;    # And now for something completely different.
         $hub->slot_contents('x');   # And now for something completely
         $hub->slot_contents('err'); # different.

       ACHTUNG!!  Because of a serious problem with Perl 5.10.0, output sent to a tied filehandle
       using "say" will not have the expected newline.  5.10.1 or later is needed.  Since 5.10.0
       is broken in so many other ways, you should really upgrade anyway.

       ACHTUNG!!  Because of a different problem with Perls 5.10.1 - 5.16.3, if you send output
       to a tied filehandle using "say", and "$\" is undefined (which is the default), "$\" will
       not be restored to "undef" after the "say"!  This means that once you've used "say" to
       print to any tied filehandle, you have corrupted the global state of your program.  Either
       start your program by setting "$\" to an empty string, which should be safe, or upgrade to
       5.18.0.

METHODS

   new
       The constructor takes no arguments.

   combined_contents
       This method returns the contents of all collected data.

   slot_contents
         my $str = $hub->slot_contents( $slot_name );

       This method returns the contents of all collected data for the named slot.

   clear_slot
         $hub->clear_slot( $slot_name );

       This sets the slot back to an empty string.

   fh
         my $fh = $hub->fh( $slot_name );

       This method returns a reference to a tied filehandle.  When printed to, output is
       collected in the named slot.

   scalar_ref
         my $str_ref = $hub->scalar_ref( $slot_name );

       This method returns a reference to scalar.  When appended to, the new content is collected
       in the named slot.  Attempting to alter the string other than by adding new content to its
       end will result in an exception.

   callback
         my $code = $hub->callback( $slot_name );
