IO::TieCombine.3pm

NAME

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

VERSION

version 1.000

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.
 
 

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.

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 );
