Read-only release history for IO-Callback
Home Page: http://metacpan.org/release/IO-Callback
"IO::Callback" provides an easy way to produce a phoney read-only filehandle that calls back to your own code when it needs data to satisfy a read. This is useful if you want to use a library module that expects to read data from a filehandle, but you want the data to come from some other source and you don't want to read it all into memory and use IO::String. use IO::Callback; my $fh = IO::Callback->new('<', sub { ... ; return $data }); my $object = Some::Class->new_from_file($fh); Similarly, IO::Callback allows you to wrap up a coderef as a write-only filehandle, which you can pass to a library module that expects to write its output to a filehandle. my $fh = IO::Callback->new('>', sub { my $data = shift ; ... }); $object->dump_to_file($fh); INSTALLATION To install this module, run the following commands: perl Build.PL ./Build ./Build test ./Build install SUPPORT AND DOCUMENTATION After installing, you can find documentation for this module with the perldoc command. perldoc IO::Callback You can also look for information at: RT, CPAN's request tracker http://rt.cpan.org/NoAuth/Bugs.html?Dist=IO::Callback AnnoCPAN, Annotated CPAN documentation http://annocpan.org/dist/IO::Callback CPAN Ratings http://cpanratings.perl.org/d/IO::Callback Search CPAN http://search.cpan.org/dist/IO::Callback COPYRIGHT AND LICENCE Copyright 1998-2005 Gisle Aas.
