Class ACSAlarmDAOImpl

java.lang.Object

com.cosylab.acs.laser.dao.ACSAlarmDAOImpl

All Implemented Interfaces:

AlarmDAO

Direct Known Subclasses:

ACSAlarmDAOImpl

public class ACSAlarmDAOImpl
extends java.lang.Object
implements AlarmDAO

Read alarms from the CDB. CDB contains one file per each possible FF and one entry per each FC and FM. It is possible to specify a default member to be used when the administrator did not specify the member.

The alarms are stored in an HashMap having the triplet as key. The default member has a triplet with a "*" replacing its name.

The sources are defined together with an alarm definition so they are read here and requested by the ACSSourceDAOImpl at startup (instead of being read again from CDB).

The initialization of the alarms is not completely done by loadAlarms because not all the info are available at this time. In fact the categories are assigned to alarms by ACSCategoryDAOImpl

For the assigning alarms to reduction rules, the class take advantage of the fact that a parent in a reduction rule never contains regular expressions nor wildcards.

Method Detail

loadAlarms

public java.util.List<FaultFamily> loadAlarms()
                                       throws java.lang.Exception

Load alarms from CDB. Read the alarms by the alarm definitions file of the CDB. The initialization of the alarms is not complete at this stage. In fact the categories are assigned to alarms when reading the categories from the CDB by ACSCategoryDAOImpl

Throws:

java.lang.Exception - In case of error while parsing XML definition files

getReductionDefinitions

public ReductionDefinitions getReductionDefinitions()

findAlarm

public Alarm findAlarm(java.lang.String alarmId)

Description copied from interface: AlarmDAO

Returns the alarm corresponding to the given id.

Specified by:

findAlarm in interface AlarmDAO

Returns:

the alarm

getAlarm

public Alarm getAlarm(java.lang.String alarmId)

Get an alarm from the cache. Get an alarm from the cache. If the alarm with the given triplet is not in the cache then it looks for a default alarm before returning null. If a default alarm is found, then a new alarm is created by cloning the default alarm. The triplet of this new alarm is set to be equal to the passed alarm ID.

Specified by:

getAlarm in interface AlarmDAO

Parameters:

alarmId - The ID of the alarm

Returns:

An alarm with the given ID if it exists in the CDB If an alarm with the give ID does not exist but a matching default alarm is defined then it return a clone of the default alarm null If the alarm is not defined in the CDB and a default alarm does not exist
