Method Detail

createFederationConsumer

protected FederationConsumerInternal createFederationConsumer(FederationConsumerInfo consumerInfo)

Description copied from class: FederationQueuePolicyManager

Create a new FederationConsumerInternal instance using the consumer information given. This is called when local demand for a matched queue requires a new consumer to be created. A subclass must override this to perform the creation of the remote consumer.

Specified by:

createFederationConsumer in class FederationQueuePolicyManager

Parameters:

consumerInfo - The FederationConsumerInfo that defines the consumer to be created.

Returns:

a new FederationConsumerInternal instance that will reside in this manager.

signalBeforeCreateFederationConsumer

protected void signalBeforeCreateFederationConsumer(FederationConsumerInfo info)

Description copied from class: FederationQueuePolicyManager

Signal any registered plugins for this federation instance that a remote Queue consumer is being created.

Specified by:

signalBeforeCreateFederationConsumer in class FederationQueuePolicyManager

Parameters:

info - The FederationConsumerInfo that describes the remote Queue consumer

signalAfterCreateFederationConsumer

protected void signalAfterCreateFederationConsumer(FederationConsumer consumer)

Description copied from class: FederationQueuePolicyManager

Signal any registered plugins for this federation instance that a remote Queue consumer has been created.

Specified by:

signalAfterCreateFederationConsumer in class FederationQueuePolicyManager

Parameters:

consumer - The FederationConsumerInfo that describes the remote Queue consumer

signalBeforeCloseFederationConsumer

protected void signalBeforeCloseFederationConsumer(FederationConsumer consumer)

Description copied from class: FederationQueuePolicyManager

Signal any registered plugins for this federation instance that a remote Queue consumer is about to be closed.

Specified by:

signalBeforeCloseFederationConsumer in class FederationQueuePolicyManager

Parameters:

consumer - The FederationConsumer that that is about to be closed.

signalAfterCloseFederationConsumer

protected void signalAfterCloseFederationConsumer(FederationConsumer consumer)

Description copied from class: FederationQueuePolicyManager

Signal any registered plugins for this federation instance that a remote Queue consumer has now been closed.

Specified by:

signalAfterCloseFederationConsumer in class FederationQueuePolicyManager

Parameters:

consumer - The FederationConsumer that that has been closed.

isPluginBlockingFederationConsumerCreate

protected final boolean isPluginBlockingFederationConsumerCreate(org.apache.activemq.artemis.core.server.Queue queue)

Description copied from class: FederationQueuePolicyManager

Query all registered plugins for this federation instance to determine if any wish to prevent a federation consumer from being created for the given Queue.

Specified by:

isPluginBlockingFederationConsumerCreate in class FederationQueuePolicyManager

Parameters:

queue - The Queue that the federation queue manager is attempting to create a remote consumer for.

Returns:

true if any registered plugin signaled that creation should be suppressed.
