Method Detail
-
addEntry
public void addEntry(UsmTimeEntry entry)
-
getEntry
public UsmTimeEntry getEntry(OctetString engineID)
-
getLocalTime
public UsmTimeEntry getLocalTime()
-
setLocalTime
public void setLocalTime(UsmTimeEntry localTime)
-
setEngineBoots
public void setEngineBoots(int engineBoots)
Sets the number of engine boots.- Parameters:
engineBoots- the number of engine boots.- Since:
- 1.2
-
getEngineTime
public int getEngineTime()
Returns the number of seconds since the value of the engineBoots object last changed. When incrementing this object's value would cause it to exceed its maximum, engineBoots is incremented as if a re-initialization had occurred, and this object's value consequently reverts to zero.- Returns:
- a positive integer value denoting the number of seconds since the engineBoots value has been changed.
- Since:
- 1.2
-
getEngineBoots
public int getEngineBoots()
The number of times that the SNMP engine has (re-)initialized itself since snmpEngineID was last configured.- Returns:
- the number of SNMP engine reboots.
-
getTime
public UsmTimeEntry getTime(OctetString engineID)
-
removeEntry
public void removeEntry(OctetString engineID)
Removes the specified engine ID from the time cache.- Parameters:
engineID- the engine ID of the remote SNMP engine to remove from this time cache.
-
checkEngineID
public int checkEngineID(OctetString engineID, boolean discoveryAllowed, int engineBoots, int engineTime)
-
checkTime
public int checkTime(UsmTimeEntry entry)
-
reset
public void reset()
