AbstractDeviceProvider (ONOS Java API (2.2.3))

java.lang.Object
- org.onosproject.net.provider.AbstractProvider
- - org.onosproject.common.net.AbstractDeviceProvider

All Implemented Interfaces:

DeviceProvider, Provider
```
public abstract class AbstractDeviceProvider
extends AbstractProvider
implements DeviceProvider
```
Base device provider capable of engaging DeviceDescriptionDiscovery driver behaviour to discover device and port details.
Assumes that derived classes will provide code to learn/generate device identifier. Also assumes that derived classes will either obtain the primordial device information sufficient to locate the correct driver, or that they will know which driver should be used, e.g. from network configuration.
