-// A pair of BroadcastChannelClient interfaces is used to represent a connection

-// This interface is used to set up connections to broadcast channels. All
-// connections to channels made from the same event loop should be made
-// through the same BroadcastChannelProvider connection to ensure correct
-// ordering of messages.
-// Typically the browser will have one instance of a BroadcastChannelProvider
-// per storage partition, to which all connections from renderers in that
-// partition are bound. This instance will then forward messages received on a
-// particular connection to all other connections in the same storage partition
-// with the same origin and name.
