Remote Method Invocation for dart

Build Status

This project provides an solution for remote method invocation in dart without the use of reflection. Since reflection is only available on the Dart VM but not on a JS VM, this solution is entirely based on code generation instead.

Getting Started

Let's say you want to invoke methods of an ExampleClass looking like this:

// in example.dart
part 'example.g.dart';
class ExampleClass implements RmiTarget {
  void someMethod() {
	print('some stuff');

  // required boilerplate for code generation
  Object invoke(Invocation invocation) =>
      _$ExampleClassInvoker.invoke(invocation, this);
  factory ExampleClass.getRemote(Context context, String uuid) =>
      _$ExampleClassRmi.getRemote(context, uuid);
  Provision provideRemote(Context context) =>
      _$ExampleClassRmi.provideRemote(context, this);

And you have the actual object present on machine A:

ExampleClass exampleObject = new ExampleClass();
/// ...setup some network connection, get a Stream and a StreamSink from it
Stream input = ...
StreamSink output = ...
Provision provision = exampleObject.provideRemote(new Context(input, output));
/// provision contains the uuid which identifies the object on this machine

On machine B:

/// Again we have the input and output you get from your network 
/// and additionally you have to provide the uuid from before
Stream input = ...
StreamSink output = ...
String uuid = ... provision.uuid // from above
ExampleClass remoteObject = ExampleClass.getRemote(new Context(input, output), uuid);
remoteObject.someMethod(); // prints 'some stuff' on the other machine


  • generator warning when no factory was implemented
  • also for part ...
  • not invocable, not proxied method annotation
  • operators
  • think about object methods, tostring hashcode
  • check lang spec for other members what else could be here
  • Serialize exceptions
  • send stack on exception
  • Add else clause to invoker to provide an error message
  • write doc
  • cleanup exports
  • write install script
  • if static getRemoteis not specified, do not write it for stub constructors simply put a waringing
  • STREAMS!!!!
  • thorw exceptions from invoke
  • Proxy does implement, extend should be possible
  • sosuchmethod...
  • reduce tests to a minimum code
  • warn on rmi non future method
  • warn for contrast metadata
  • class hierarchy metadata
  • pass stream and future null arguments
