// This file contains the PeerConnection interface as defined in
// http://dev.w3.org/2011/webrtc/editor/webrtc.html#peer-to-peer-connections.
// Applications must use this interface to implement peerconnection.
// PeerConnectionFactory class provides factory methods to create
// peerconnection, mediastream and media tracks objects.
//
// The Following steps are needed to setup a typical call.
// 1. Create a PeerConnectionFactoryInterface. Check constructors for more
// information about input parameters.
// 2. Create a PeerConnection object. Provide a configuration string which
// points either to stun or turn server to generate ICE candidates and provide
// an object that implements the PeerConnectionObserver interface.
// Now PeerConnection will startcollecting ICE candidates.
// 3. Create local MediaStream and MediaTracks using the PeerConnectionFactory
// and add it to PeerConnection by calling AddStream.
// 4. Once all mediastreams are added to peerconnection, call
// CommitStreamChanges. Now PeerConnection starts generating an offer based on
// the local mediastreams.
// 5. When PeerConnection have generated the ICE candidates it will call the
// observer OnSignalingMessage callback with the initial offer.
// 6. When an Answer from peer received it must be supplied to the
// PeerConnection by calling ProcessSignalingMessage.
// At this point PeerConnection knows remote capabilities and ICE candidates.
// Media will start flowing to the remote peer.
// The Receiver of a call can decide to accept or reject the call.
// This decision will be taken by the application not peerconnection.
// If application decides to accept the call
// 1. Create PeerConnectionFactoryInterface if it doesn't exist.
// 2. Create new PeerConnection
// 3. Provide the remote offer to the new PeerConnection object by calling
// ProcessSignalingMessage.
// 4. PeerConnection will call the observer function OnAddStream with remote
// MediaStream and tracks information.
// 5. PeerConnection will call the observer function OnSignalingMessage with
// local ICE candidates in a answer message.
// 6. Application can add it's own MediaStreams by calling AddStream.
// When all streams have been added the application must call
// CommitStreamChanges. Streams can be added at any time after the
// PeerConnection object have been created.

// Originally these classes are copied from Chromium.
//
// A smart pointer class for reference counted objects. Use this class instead
// of calling AddRef and Release manually on a reference counted object to
// avoid common memory leaks caused by forgetting to Release an object
// reference. Sample usage:
//
// class MyFoo : public RefCounted<MyFoo> {
// ...
// };
//
// void some_function() {
// scoped_refptr<MyFoo> foo = new MyFoo();
// foo->Method(param);
// // |foo| is released when this function returns
// }
//
// void some_other_function() {
// scoped_refptr<MyFoo> foo = new MyFoo();
// ...
// foo = NULL; // explicitly releases |foo|
// ...
// if (foo)
// foo->Method(param);
// }
//
// The above examples show how scoped_refptr<T> acts like a pointer to T.
// Given two scoped_refptr<T> classes, it is also possible to exchange
// references between the two objects, like so:
//
// {
// scoped_refptr<MyFoo> a = new MyFoo();
// scoped_refptr<MyFoo> b;
//
// b.swap(a);
// // now, |b| references the MyFoo object, and |a| references NULL.
// }
//
// To make both |a| and |b| in the above example reference the same MyFoo
// object, simply use the assignment operator:
//
// {
// scoped_refptr<MyFoo> a = new MyFoo();
// scoped_refptr<MyFoo> b;
//
// b = a;
// // now, |a| and |b| each own a reference to the same MyFoo object.
// }
