Class RemoteListenerSource

java.lang.Object

com.openxc.sources.BaseVehicleDataSource

com.openxc.sources.RemoteListenerSource

All Implemented Interfaces:

DataPipeline.Operator, VehicleDataSource

public class RemoteListenerSource
extends BaseVehicleDataSource

Pass messages from a VehicleService to an in-process callback. This source is a bit of a special case - it's used by the VehicleManager to inject message updates from a VehicleService into an in-process data pipeline. By using the same workflow as on the remote process side, we can share code between remote and in-process data sources and sinks. This makes adding new sources and sinks possible for end users, since the VehicleService doesn't need to have every possible implementation.
