Class AbstractAMQMessageDelegate

java.lang.Object

org.apache.qpid.client.message.AbstractAMQMessageDelegate

All Implemented Interfaces:

AMQMessageDelegate

Direct Known Subclasses:

AMQMessageDelegate_0_10, AMQMessageDelegate_0_8

public abstract class AbstractAMQMessageDelegate
extends Object
implements AMQMessageDelegate

This abstract class provides exchange lookup functionality that is shared between all MessageDelegates. Update facilities are provided so that the 0-10 code base can update the mappings. The 0-8 code base does not have the facility to update the exchange map so it can only use the default mappings. That said any updates that a 0-10 client performs will also benefit any 0-8 connections in this VM.

Constructor Detail

AbstractAMQMessageDelegate

protected AbstractAMQMessageDelegate(long deliveryTag)

Method Detail

getDeliveryTag

public long getDeliveryTag()

Get the AMQ message number assigned to this message

Specified by:

getDeliveryTag in interface AMQMessageDelegate

Returns:

the message number

generateDestination

protected AMQDestination generateDestination(String exchange,
                                 String routingKey)

Called when a Destination is requried. This will create the AMQDestination that is the correct type and value based on the incomming values.

Parameters:

exchange - The exchange name

routingKey - The routing key to be used for the Destination

Returns:

AMQDestination of the correct subtype

updateExchangeType

protected static void updateExchangeType(String exchange,
                      String newtype)

Update the exchange name to type mapping. If the newType is not known then an UNKNOWN_TYPE is created. Only if the exchange is of a known type: amq.direct, amq.topic, amq.fanout can we create a suitable AMQDestination representation

Parameters:

exchange - the name of the exchange

newtype - the AMQP exchange class name i.e. direct

exchangeMapContains

protected static boolean exchangeMapContains(String exchange)

Accessor method to allow lookups of the given exchange name. This check allows the prevention of extra work required such as asking the broker for the exchange class name.

Parameters:

exchange - the exchange name to lookup

Returns:

true if there is a mapping for this exchange

acknowledgeThis

public void acknowledgeThis()
                     throws javax.jms.JMSException

Specified by:

acknowledgeThis in interface AMQMessageDelegate

Throws:

javax.jms.JMSException

acknowledge

public void acknowledge()
                 throws javax.jms.JMSException

Specified by:

acknowledge in interface AMQMessageDelegate

Throws:

javax.jms.JMSException

setAMQSession

public void setAMQSession(AMQSession<?,?> s)

The session is set when CLIENT_ACKNOWLEDGE mode is used so that the CHANNEL ACK can be sent when the user calls acknowledge()

Specified by:

setAMQSession in interface AMQMessageDelegate

Parameters:

s - the AMQ session that delivered this message

getAMQSession

public AMQSession<?,?> getAMQSession()

Specified by:

getAMQSession in interface AMQMessageDelegate

convertToAddressBasedDestination

protected javax.jms.Destination convertToAddressBasedDestination(String exchange,
                                                     String routingKey,
                                                     String subject,
                                                     boolean useNodeTypeForDestinationType,
                                                     int type)
