Method Detail

createConsumerInfo

protected FederationGenericConsumerInfo createConsumerInfo(org.apache.activemq.artemis.core.server.impl.AddressInfo address)

Description copied from class: FederationAddressPolicyManager

Create a new FederationConsumerInfo based on the given AddressInfo and the configured FederationReceiveFromAddressPolicy. A subclass must override this method to return a consumer information object with the data used be that implementation.

Specified by:

createConsumerInfo in class FederationAddressPolicyManager

Parameters:

address - The AddressInfo to use as a basis for the consumer information object.

Returns:

a new FederationConsumerInfo instance based on the given address.

generateQueueName

protected String generateQueueName(org.apache.activemq.artemis.core.server.impl.AddressInfo address)

createFederationConsumer

protected FederationConsumerInternal createFederationConsumer(FederationConsumerInfo consumerInfo)

Description copied from class: FederationAddressPolicyManager

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. This method by default will call the configured consumer factory function that was provided when the manager was created, a subclass can override this to perform additional actions for the create operation.

Specified by:

createFederationConsumer in class FederationAddressPolicyManager

Parameters:

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

Returns:

a new FederationConsumerInternal instance that will reside in this manager.

testIfAddressMatchesPolicy

protected boolean testIfAddressMatchesPolicy(org.apache.activemq.artemis.core.server.impl.AddressInfo addressInfo)

Description copied from class: FederationAddressPolicyManager

Performs the test against the configured address policy to check if the target address is a match or not. A subclass can override this method and provide its own match tests in combination with the configured matching policy.

Overrides:

testIfAddressMatchesPolicy in class FederationAddressPolicyManager

Parameters:

addressInfo - The address that is being tested for a policy match.

Returns:

true if the address given is a match against the policy.

signalBeforeCreateFederationConsumer

protected void signalBeforeCreateFederationConsumer(FederationConsumerInfo info)

Description copied from class: FederationAddressPolicyManager

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

Specified by:

signalBeforeCreateFederationConsumer in class FederationAddressPolicyManager

Parameters:

info - The FederationConsumerInfo that describes the remote Address consumer

signalAfterCreateFederationConsumer

protected void signalAfterCreateFederationConsumer(FederationConsumer consumer)

Description copied from class: FederationAddressPolicyManager

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

Specified by:

signalAfterCreateFederationConsumer in class FederationAddressPolicyManager

Parameters:

consumer - The FederationConsumerInfo that describes the remote Address consumer

signalBeforeCloseFederationConsumer

protected void signalBeforeCloseFederationConsumer(FederationConsumer consumer)

Description copied from class: FederationAddressPolicyManager

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

Specified by:

signalBeforeCloseFederationConsumer in class FederationAddressPolicyManager

Parameters:

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

signalAfterCloseFederationConsumer

protected void signalAfterCloseFederationConsumer(FederationConsumer consumer)

Description copied from class: FederationAddressPolicyManager

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

Specified by:

signalAfterCloseFederationConsumer in class FederationAddressPolicyManager

Parameters:

consumer - The FederationConsumer that that has been closed.

isPluginBlockingFederationConsumerCreate

protected final boolean isPluginBlockingFederationConsumerCreate(org.apache.activemq.artemis.core.server.impl.AddressInfo address)

Description copied from class: FederationAddressPolicyManager

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 FederationAddressPolicyManager

Parameters:

address - The address on which the manager is intending to create a remote consumer for.

Returns:

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

isPluginBlockingFederationConsumerCreate

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

Description copied from class: FederationAddressPolicyManager

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 FederationAddressPolicyManager

Parameters:

divert - The Divert that triggered the manager to attempt to create a remote consumer.

queue - The Queue that triggered the manager to attempt to create a remote consumer.

Returns:

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

isPluginBlockingFederationConsumerCreate

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

Description copied from class: FederationAddressPolicyManager

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 FederationAddressPolicyManager

Parameters:

queue - The Queue that triggered the manager to attempt to create a remote consumer.

Returns:

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