Class WorkingMemoryLogger

java.lang.Object
  org.drools.audit.WorkingMemoryLogger

All Implemented Interfaces:: java.util.EventListener, AgendaEventListener, WorkingMemoryEventListener

Direct Known Subclasses:: WorkingMemoryFileLogger

public abstract class WorkingMemoryLogger
extends java.lang.Object
implements WorkingMemoryEventListener, AgendaEventListener
extends java.lang.Object
implements WorkingMemoryEventListener, AgendaEventListener

A logger of events generated by a working memory. It listens to the events generated by the working memory and creates associated log event (containing a snapshot of the state of the working event at that time). Filters can be used to filter out unwanted events. Subclasses of this class should implement the logEventCreated(LogEvent) method and store this information, like for example log to file or database.

Constructor Summary

WorkingMemoryLogger(WorkingMemory workingMemory)
          Creates a new working memory logger for the given working memory.

Method Summary

void activationCancelled(ActivationCancelledEvent event)


void activationCreated(ActivationCreatedEvent event)


void addFilter(ILogEventFilter filter)
          Adds the given filter to the list of filters for this event log.

void afterActivationFired(AfterActivationFiredEvent event)


void beforeActivationFired(BeforeActivationFiredEvent event)


void clearFilters()
          Clears all filters of this event log.

abstract void logEventCreated(LogEvent logEvent)
          This method is invoked every time a new log event is created.

void objectAsserted(ObjectAssertedEvent event)


void objectModified(ObjectModifiedEvent event)


void objectRetracted(ObjectRetractedEvent event)


void removeFilter(ILogEventFilter filter)
          Removes the given filter from the list of filters for this event log.

Constructor Detail

WorkingMemoryLogger

public WorkingMemoryLogger(WorkingMemory workingMemory)

Creates a new working memory logger for the given working memory.

Parameters:: workingMemory -

Method Detail

logEventCreated

public abstract void logEventCreated(LogEvent logEvent)

This method is invoked every time a new log event is created. Subclasses should implement this method and store the event, like for example log to a file or database.

Parameters:: logEvent -

addFilter

public void addFilter(ILogEventFilter filter)

Adds the given filter to the list of filters for this event log. A log event must be accepted by all the filters to be entered in the event log.

Parameters:: filter - The filter that should be added.

removeFilter

public void removeFilter(ILogEventFilter filter)

Removes the given filter from the list of filters for this event log. If the given filter was not a filter of this event log, nothing happens.

Parameters:: filter - The filter that should be removed.

clearFilters

public void clearFilters()

Clears all filters of this event log.
