HeartbeatService

A simple service that generates periodic events. Used to test connections and as a skeleton for implementation of new event services.

Generated events

• Service type: Generic
• Event types: Update
• Event data fields: position, orientation.

Position and orientation contain an increasing event sequence number pls a floating point offset. This is used to test the correctness of event streaming modules like oinputserver and omicronConnector. The structure of the data is as follows:

• position[= sequence number
• position[0][0]) = sequence number + 0.1
• position[= sequence number + 0.2
• orientation0 = sequence number + 0.3
• orientation[= sequence number + 0.4
• orientation0 = sequence number + 0.5
• orientation[0] = sequence number + 0.6

Configuration parameters

• rate (float): the number of events per seconds that the service will generate
