Sending Events

You can generate and send your own events from your custom nodes.
For sending an event just call raiseEvent() with an event you have prepared.

var eventInformation = new EventInformation(
				channelIndex, 
				"accuweather", 
				"weather", 
				outData,
				startSampleIndex, 
				endSampleIndex,
                "",
                tags
			)
raiseEvent(eventInformation);

var EventInformation = function (
    ChannelIndex,
    ServiceName,
    EventName,
    Data,
    StartSampleIndex,
    EndSampleIndex,
    GroupId,
    Tags)
