Class CachedDeviceList

java.lang.Object

org.jivesoftware.smackx.omemo.internal.CachedDeviceList

All Implemented Interfaces:

java.io.Serializable

public class CachedDeviceList
extends java.lang.Object
implements java.io.Serializable

This class is used to represent device lists of contacts. There are active devices (a set of device ids, which was published with the last device list update) and inactive devices (set of devices that once were active, but are not included in recent list updates). Both kinds are cached by the client. When a device that was active in the last update is not included in a new update, it becomes an inactive device. Vice versa, inactive devices can also become active again, by being included in the latest device list update.

The client ensures, that his own device id is on the list of active devices, as soon as he gets online.
