- Method Detail
  - getServiceProperty
```
Object getServiceProperty(String propKey)
```
    Returns the current value of the specified property. The method will return the same value as ServiceReference.getProperty(String) for the service reference of this device.
    This method must continue to return property values after the device service has been unregistered.
    
    Parameters:
    propKey - The property key.
    
    Returns:
    The property value or null if the property key cannot be mapped to a value.
  - getServicePropertyKeys
```
String[] getServicePropertyKeys()
```
    Returns an array with all device service property keys. The method will return the same value as ServiceReference.getPropertyKeys() for the service reference of this device. The result cannot be null.
    
    Returns:
    An array with all device service property keys, cannot be null.
  - remove
```
void remove()
            throws DeviceException
```
    Removes this device.
    The method must synchronously:
    - Remove the device from the device network.
    - Set the device status to STATUS_REMOVED.
    - Unregister the device service from the OSGi service registry.
    The caller should release the device service after successful execution, because the device will not be operational.
    Throws:
    
    DeviceException - If an operation error is available.
    
    UnsupportedOperationException - If the operation is not supported over this device.
    
    SecurityException - If the caller does not have the appropriate DevicePermission(this device, DevicePermission.REMOVE) and the Java Runtime Environment supports permissions.
    
    IllegalStateException - If this device service object has already been unregistered.
