NAME

       AnyEvent::ForkObject - Async access on objects.

SYNOPSIS

           use AnyEvent::ForkObject;
           use DBI;

           my $fo = new AnyEvent::ForkObject;

           $fo->do(
               module => 'DBI',
               method => 'connect',
               args => [ 'dbi:mysql...' ],
               cb => sub {
                   my ($status, $dbh) = @_;

                   $dbh->selectrow_array('SELECT ?', undef, 1 + 1, sub {
                       my ($status, $result) = @_;
                       print "$result\n";   # prints 2
                   });
               }
           );

           use AnyEvent::Tools qw(async_repeat);

           $dbh->prepare('SELECT * FROM tbl', sub {
               my ($status, $sth) = @_;
               $sth->execute(sub {
                   my ($status, $rv) = @_;

                   # fetch 30 rows
                   async_repeat 30 => sub {
                       my ($guard) = @_;

                       $sth->fetchrow_hashref(sub {
                           my ($status, $row) = @_;
                           undef $guard;

                           # do something with $row
                       });
                   };

               });
           });

DESCRIPTION

       There are a lot of modules that provide object interface. Using the module You can use
       them in async mode.

METHODS

   new
       Constructor. Creates an instance that contains fork jail.

   do
       Creates an object inside jail. It receives the following named arguments:

       require
           Do require inside jail. If the argument is exists, module, method and wantarray
           arguments will be ignored.

       module
           Module name. For example 'DBI'.

       method
           Constructor name. Default value is 'new'.

       wantarray
           Context for method. Default is 0 (SCALAR).

       cb  Done callback. The first argument is a status:

           die The method has thrown exception. The next argument contains $@.

           fatal
               A fatal error was occured (for example fork jail was killed).

           ok  Method has done. The following arguments contain all data that were returned by
               the method.

       If "method" returns blessed object, it will provide all its methods in modified form. Each
       method will receive one or two additional arguments:

       result callback
           A callback that will be called after method has done.

       wantarray
           Context flag for method. Default value is 0 (SCALAR).

       All objects provide additional method fo_attr to access their field.  Example:

           # set attribute
           $dbh->fo_attr(RaiseError => 1, sub { my ($status, $attr) = @_; ... });

           # get attribute
           $dbh->fo_attr('RaiseError', sub { my ($status, $attr) = @_; ... });
