org.apache.activemq.artemis.protocol.amqp.connect.federation.AMQPFederationTarget

All Implemented Interfaces:

Federation, FederationInternal

public class AMQPFederationTarget
extends AMQPFederation

This is the receiving side of an AMQP broker federation that occurs over an inbound connection from a remote peer. The federation target only comes into existence once a remote peer connects and successfully authenticates against a control link validation address. Only one federation target is allowed per connection.

Parameters:

cause - The error that caused the resource creation to fail.

signalError

protected void signalError(Exception cause)

Description copied from class: AMQPFederation

Error signaling API that must be implemented by the specific federation implementation to handle errors encountered during normal operations.

Specified by:

signalError in class AMQPFederation

Parameters:

cause - The error that caused the operation to fail.
