Class ConnectionStatusMessageMapper

java.lang.Object

org.eclipse.ditto.services.connectivity.mapping.AbstractMessageMapper

org.eclipse.ditto.services.connectivity.mapping.ConnectionStatusMessageMapper

All Implemented Interfaces:

MessageMapper

public class ConnectionStatusMessageMapper
extends AbstractMessageMapper

This mapper extracts the headers creation-time and ttd from the message and builds a ModifyFeature command from it. The default featureId is ConnectionStatus but can be changed via the mapping configuration. The thingId must be set in the mapping configuration. It can either be a fixed Thing ID or it can be resolved from the message headers by using a placeholder e.g. {{ header:device_id }}.
