DeviceDescriptionDiscovery (ONOS Java API (2.5.0))

All Superinterfaces:

Behaviour, HandlerBehaviour
```
public interface DeviceDescriptionDiscovery
extends HandlerBehaviour
```
Handler behaviour capable of creating device and port descriptions. These descriptions should be appropriately annotated to support downstream projections of the respective devices and their ports.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`DeviceDescription`	`discoverDeviceDetails()`	Returns a device description appropriately annotated to support downstream model extension via projections of the resulting device, as in the following example.
`List<PortDescription>`	`discoverPortDetails()`	Returns a list of port descriptions appropriately annotated to support downstream model extension via projections of their parent device, as in the following example.
`default void`	`discoverPortDetails(Consumer<PortDescription> consumer)`	Invoke given lamda function when port descriptions are discovered.

DeviceDescription discoverDeviceDetails()
```
    Returns a device description appropriately annotated to support downstream model extension via projections of the resulting device, as in the following example.
    MicrowaveDevice device = deviceService.get(id).as(MicrowaveDevice.class);
    Returns:
    
    annotated device description

```
List<PortDescription> discoverPortDetails()
```
    Returns a list of port descriptions appropriately annotated to support downstream model extension via projections of their parent device, as in the following example.

    Returns:
    
    annotated device description
  - discoverPortDetails
```
default void discoverPortDetails(Consumer<PortDescription> consumer)
```
    Invoke given lamda function when port descriptions are discovered.
    
    Parameters:
    
    consumer - consumer to process port description
