xtUML interfaces can be uni-directional or bi-directional. From this graphic you can see small arrows in the port boxes indicating whether the port contains messages that are inbound, outbound or both. The LocationProvider and LocationUtil interfaces are uni-directional and on the Tracking component the messages are all outbound. The UI and HeartRateProvider interfaces contain messages in both directions.
