Detailed Description

The OpenNI::DeviceDisconnectedListener class provides a means of registering for, and responding to when a device is disconnected.

onDeviceDisconnected is called when a device is removed from the system. 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() should be called again in order to use this device.

To use this class, you should write a new class that inherits from it, and override the onDeviceDisconnected method. Once you instantiate your class, use the OpenNI::addDeviceDisconnectedListener() 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::removeDeviceDisconnectedListener() function is also provided, if you want to have your class stop listening to these events for any reason.

Callback function for the onDeviceDisconnected event. This function will be called whenever this event occurs. When this happens, a pointer to the DeviceInfo object for the newly disconnected 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() should be called again in order to use this device.
