Class EventConfData

java.lang.Object
  org.opennms.netmgt.eventd.datablock.EventConfData

public class EventConfData
extends Object

 The information read from the eventconf.xml is stored here. It maintains
  a map,  keyed with 'EventKey's. 
 
  It also has an UEI to 'EventKey'list map - this mapping fastens the lookup 
  for OpenNMS internal events when different masks are configured for the
  same UEI.
 
  When a lookup is to be done for an 'Event',  
  - its 'key' is used to get a lookup,
  - if no match is found for the key, UEI is used to lookup the keys that got added for that UEI
    and the first best fit in the event map for any of the UEI keys are used
  - if there is still no match at this point, all keys in the eventconf are iterated through to
    find a match

Constructor Summary

EventConfData()
Default constructor - allocate the maps

Method Summary

void	clear() Clear out the data
protected boolean	eventValuePassesMaskValue(String eventvalue, List maskValues) Check whether the eventvalue passes any of the mask values Mask values ending with a '%' only need to be a substring of the eventvalue for the eventvalue to pass the mask Enhanced 2005/08/31 to allow regular expression in eventconf.
Event	getEvent(Event event) Get the right configuration for the event - the eventkey is used first.
Event	getEventByUEI(String uei) Get the event with the specified uei
void	put(Event event) Add an event - add to the 'EventKey' map using the event mask by default.
void	put(EventKey key, Event event) Add an event with the specified key

Method Detail

eventValuePassesMaskValue

protected boolean eventValuePassesMaskValue(String eventvalue,
                                            List maskValues)

Check whether the eventvalue passes any of the mask values Mask values ending with a '%' only need to be a substring of the eventvalue for the eventvalue to pass the mask Enhanced 2005/08/31 to allow regular expression in eventconf.

Returns:

true if the values passes the mask

put

public void put(Event event)

Add an event - add to the 'EventKey' map using the event mask by default. If the event has snmp information, add using the snmp EID

Parameters:

event - the org.opennms.netmgt.xml.eventconf.Event

put

public void put(EventKey key,
                Event event)

Add an event with the specified key

Parameters:

key - the EventKey for this event

event - the org.opennms.netmgt.xml.eventconf.Event

getEvent

public Event getEvent(Event event)

 Get the right configuration for the event - the eventkey is used first.
  If no match is found, the event's uei to keylist is iterated through, and these keys
  used to lookup the event map. if still no match is found, all eventconf
  keys are iterated through to find a match. The first successful match is returned.
 
  
 
 NOTE:
 
 The first right config event that the event matches is returned.
  The ordering of the configurations is the responsibility of the user
 

Parameters:

event - the event which is to be looked up

getEventByUEI

public Event getEventByUEI(String uei)

Get the event with the specified uei

Parameters:

uei - the uei

clear

public void clear()

Clear out the data
