# Interface OpenNI.DeviceConnectedListener

Enclosing class:
  `OpenNI`

public static interface OpenNI.DeviceConnectedListener
The OpenNI.DeviceConnectedListener interface provides a means of registering for, and responding to when a device is connected. onDeviceConnected is called whenever a new device is connected to the system (ie this event would be triggered when a new sensor is manually plugged into the host system running the application) To use this class, you should write a new class that inherits from it, and override the onDeviceConnected method. Once you instantiate your class, use the `OpenNI.addDeviceConnectedListener(org.openni.OpenNI.DeviceConnectedListener)` function to add your listener object to OpenNI's list of listeners. Your handler function will then be called whenever the event occurs. A `OpenNI.removeDeviceConnectedListener(org.openni.OpenNI.DeviceConnectedListener)` function is also provided, if you want to have your class stop listening to these events for any reason.

## Method Details

### onDeviceConnected

void onDeviceConnected(DeviceInfo info)
Callback function for the onDeviceConnected event. This function will be called whenever this event occurs. When this happens, a pointer to the `DeviceInfo` object for the newly connected device will be supplied. Note that once a device is removed, if it was opened by a `Device` object, that object can no longer be used to access the device, even if it was reconnected. Once a device was reconnected, `Device.open(String)` should be called again in order to use this device. If you wish to open the new device as it is connected, simply query the provided DeviceInfo object to obtain the URI of the device, and pass this URI to the `Device.open(String)` function.
