JmsAuditEventHandler

@Inject
public JmsAuditEventHandler(JmsContextManager jmsContextManager,
 BatchPublisherFactory publisherFactory,
 JmsAuditEventHandlerConfiguration configuration,
 EventTopicsMetaData eventTopicsMetaData)
                     throws ResourceException

Creates a new AuditEventHandler instance that publishes JMS messages on a JMS Topic for each Audit event.

Parameters:

jmsContextManager - optional injected JmsContextManager.

publisherFactory - the batch publisher factory or null

configuration - Configuration parameters that can be adjusted by system administrators.

eventTopicsMetaData - Meta-data for all audit event topics.

Throws:

ResourceException - If JMS connections cannot be established.

Method Details

startup

public void startup()
             throws ResourceException

Creates the JMS Topic and ConnectionFactory from the context configuration settings and opens the JMS connection.

Specified by:

startup in interface AuditEventHandler

Throws:

ResourceException - if starting the AuditEventHandler fails

shutdown

public void shutdown()
              throws ResourceException

Closes the JMS connection.

Specified by:

shutdown in interface AuditEventHandler

Throws:

ResourceException - if closing the AuditEventHandler fails

queryEvents

public Promise<QueryResponse,ResourceException> queryEvents(org.forgerock.services.context.Context context,
 String topic,
 QueryRequest queryRequest,
 QueryResourceHandler queryResourceHandler)

Returns NotSupportedException as query is not implemented for JMS.

Query some events from the provided topic.

Specified by:

queryEvents in interface AuditEventHandler

Parameters:

context - The context chain that initiated the event.

topic - The topic on which query is performed.

queryRequest - The request with the query.

queryResourceHandler - The handler to process responses for the query.

Returns:

NotSupportedException as query is not implemented for JMS.

readEvent

public Promise<ResourceResponse,ResourceException> readEvent(org.forgerock.services.context.Context context,
 String topic,
 String resourceId)

Returns NotSupportedException as read is not implemented for JMS.

Reads an event with the provided resource id from the provided topic.

Specified by:

readEvent in interface AuditEventHandler

Parameters:

context - The context chain that initiated the event.

topic - The topic where event is read.

resourceId - The identifier of the event.

Returns:

NotSupportedException as read is not implemented for JMS.

publishEvent

public Promise<ResourceResponse,ResourceException> publishEvent(org.forgerock.services.context.Context context,
 String topic,
 JsonValue event)

Description copied from interface: AuditEventHandler

Publishes an event to the provided topic.

Note for implementors, it is imperative that the supplied event is not modified in any way as this may cause undesirable behaviour where multiple handlers are configured. If the event must be modified, then make a copy of it and work with that.

Specified by:

publishEvent in interface AuditEventHandler

Parameters:

context - The context chain that initiated the event.

topic - The topic where to publish the event.

event - The event to publish - which should be considered immutable.

Returns:

a promise with either a response or an exception

addToBatch

Description copied from interface: BatchConsumer

Adds an audit event to a batch payload.

Specified by:

addToBatch in interface BatchConsumer

Parameters:

topic - event topic

event - event JSON payload

payload - batch payload

Throws:

BatchException - indicates failure to add-to-batch

publishBatch

public Promise<Void,BatchException> publishBatch(String payload)

Description copied from interface: BatchConsumer

Publishes the batch payload.

Specified by:

publishBatch in interface BatchConsumer

Parameters:

payload - batch payload

Returns:

a simple promise encapsulating any potential batch exception
