MessageBus
Message Bus is a low level API used to communicate between the UI and the background. Communication is based on a channel abstraction. Messages published in a given channel to one MessageBusSink are received on the same channel by the corresponding MessageBusSource.

abstract class MessageBus implements MessageBusSource, MessageBusSink {
abstract initChannel(channel: string, runInZone?: boolean): void
abstract attachToZone(zone: NgZone): void
abstract from(channel: string): EventEmitter<any>
abstract to(channel: string): EventEmitter<any>
}
方法
Sets up a new channel on the MessageBus. MUST be called before calling from or to on the channel. If runInZone is true then the source will emit events inside the angular zone and the sink will buffer messages and send only once the zone exits. if runInZone is false then the source will emit events inside the global zone and the sink will send messages immediately. |
Assigns this bus to the given zone. Any callbacks attached to channels where runInZone was set to true on initialization will be executed in the given zone. |
