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.

virtual void openni::OpenNI::DeviceDisconnectedListener::onDeviceDisconnected ( const DeviceInfo )
pure virtual

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.
