IO::TieCombine(3pm)					User Contributed Perl Documentation				       IO::TieCombine(3pm)

NAME
IO::TieCombine - produce tied (and other) separate but combined variables VERSION
version 1.002 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. "; 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. 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 ); AUTHOR
