Constructor Details

SystemProcessWatchdogProcessor

public SystemProcessWatchdogProcessor()

Constructor for SystemProcessWatchdogProcessor.

Method Details

configure

public void configure(Record record,
 org.apache.commons.configuration.HierarchicalConfiguration config)

Configures the internals of value processor, provides reference to parent record and to configuration with root inside processor tag. Parent record is not yet initialized, so does not have reference to Database, the Database reference will be available during activate call.

Specified by:

configure in interface ValueProcessor

Overrides:

configure in class DefaultAlarmProcessor

Parameters:

record - the parent record.

config - configuration with room inside processor tag.

propertyChange

public void propertyChange(PropertyChangeEvent evt)

Specified by:

propertyChange in interface PropertyChangeListener

Overrides:

propertyChange in class DefaultAlarmProcessor

process

public void process()

Called by Database in interval set by the trigger parameter in milliseconds. Not called if trigger in 0.

Specified by:

process in interface ValueProcessor

Overrides:

process in class AbstractValueProcessor

updateAlarmStatus

public void updateAlarmStatus()

Alarm processor should check connections and other parameters and update alarm status.

This method should be called by processor itself, for example from PropertyChange update loop.

As well could be called by asynchronous update loop, which does the supress_time handling.

Overrides:

updateAlarmStatus in class DefaultAlarmProcessor
