Class UsmUserEntry

java.lang.Object
org.snmp4j.security.UsmUserEntry
All Implemented Interfaces:
Serializable, Comparable<UsmUserEntry>
public class UsmUserEntry extends Object implements Serializable, Comparable<UsmUserEntry>
The UsmUserEntry class represents a user in the Local Configuration Datastore (LCD). The embedded UsmUser can be localized for an engine ID or not. The localization state is determined by UsmUser.isLocalized(). Adding a non-localized user to the LCD does only makes sense if (1) USM.isEngineDiscoveryEnabled() is true and this user should be used to access command responders without yet unknown engine ID or if (2) this user should be used to receive incoming notifications from agents with (yet) unknown authoritative engine IDs. If a user can be used for discoveries of type (1) and/or (2) can be defined by
invalid @link 
{@link UsmUser#
}
