This event indicates that a new object is available on the device. |

This event is sent after a previously existing object has been removed from the device. The object might be a content object, for example, an image file was deleted; or it might be a functional object, for example, a new storage device was unplugged from the device. |

This event is sent to request an application to transfer a particular object from the device. The object is usually a content object, for example, an image file. |

This event is sent after an object has been updated, and any connected client should refresh its view of that object. |
