Interface StreamingDataHandler

public interface StreamingDataHandler

Class the represents a streaming data listener for data being sent over a TurbineStreamingConnection

The listener must be able to

• Respond to regular data events where the data may be sorted by the streaming connection.
• Respond to delete events for data that was higher priority earlier on but has now been superceded by another data type
• Respond to pings where there is no activity.

Note that if the StreamingDataHandler throws an Exception during this process, then the TurbineStreamingConnection will stop.
