Class PeerConnection

java.lang.Object
com.codename1.webrtc.PeerConnection
public final class PeerConnection extends Object

One end of a call: the media this device sends, what it receives, and the network path between the two.

The sequence is the standard one. The caller adds its tracks, creates an offer, sets it as its local description and sends it; the callee sets it as its remote description, adds its own tracks, creates an answer, sets that locally and sends it back; the caller sets it as remote. Meanwhile both sides send each other every candidate their listener is given. Carrying the descriptions and candidates is the app's job -- over its own server, a WebSocket, anything -- and nothing here sends them.
