NAME

RPC::Object - A lightweight implementation for remote procedure calls

SYNOPSIS

On server

  use RPC::Object::Broker;
  $b = $RPC::Object::Broker->new(preload => \@preload_modules);
  $b->start();

On client

  use RPC::Object;
  $o = RPC::Object->new("$host:$port", 'method_a', 'TestModule');
  my $ans1 = $o->method_b($arg1, $arg2);
  my @ans2 = $o->method_c($arg3, $arg4);

  # To access the global instance
  # allocate and initialize first,
  RPC::Object->new("$host:$port", 'method_a', 'TestModule');
  ...
  $global = RPC::Object->get_instance("$host:$port", 'TestModule');

TestModule

  package TestModule;
  use threads;
  ...
  sub method_a {
      my $class = shift;
      my $self : shared;
      ...
      return bless $self, $class;
  }  }

Please see more examples in the test scripts.

DESCRIPTON

RPC::Object is designed to be very simple and only works between Perl codes, This makes its implementation only need some core Perl modules, e.g. Socket and Storable.

Other approaches like SOAP or XML-RPC are too heavy for simple tasks.

Thread awareness

All modules and objects invoked by RPC::Object should aware the multi-threaded envrionment.

Constructor and Destructor

The Module could name its constructor any meaningful name. it do not have to be new, or create, etc...

There is no guarantee that the destructor will be called as expected.

Global instance

To allocate global instances, use the RPC::Object::new() method. Then use the RPC::Object::get_instance() method to access them.

KNOW ISSUES

Scalars leaked warning

This is expected for now. The walkaround is to close STDERR.

Need re-bless RPC::Object

threads::shared prior to 0.95 does not support bless on shared refs, if an <RPC::Object> is passed across threads, it may need re-bless to RPC::Object.
