Class AmqpSender

java.lang.Object

org.apache.activemq.transport.amqp.protocol.AmqpAbstractLink<org.apache.qpid.proton.engine.Sender>

org.apache.activemq.transport.amqp.protocol.AmqpSender

All Implemented Interfaces:

AmqpLink, AmqpResource

public class AmqpSender
extends AmqpAbstractLink<org.apache.qpid.proton.engine.Sender>

An AmqpSender wraps the AMQP Sender end of a link from the remote peer which holds the corresponding Receiver which receives messages transfered across the link from the Broker. An AmqpSender is in turn a message consumer subscribed to some destination on the broker. As messages are dispatched to this sender that are sent on to the remote Receiver end of the lin.
