| This is an example showing a Dependency Manager "Adapter" in action. Two kinds of services are |
| registered in the registry: some Device, and some DeviceParameter services. For each Device (having |
| a given id), there is also a corresponding "DeviceParameter" service, having the same id. |
| |
| Then a "DeviceAccessImpl" adapter service is defined: it is used to "adapt" the "Device" service to |
| a "DeviceAccess" service, which provides the union of each pair of Device/DeviceParameter having the |
| same device.id . The adapter also dynamically propagate the service properties of the adapted Device |
| service. |
| |
| Start the test by clicking on the "device.api.bndrun" descriptor, then run it, and type under gogo shell: |
| |
| g! log warn |
| |
| You will then see: |
