AmqpConnection

public AmqpConnection(AmqpTransport transport,
              BrokerService brokerService)

Method Detail

getConnectionCapabilitiesOffered

protected org.apache.qpid.proton.amqp.Symbol[] getConnectionCapabilitiesOffered()

Load and return a []Symbol that contains the connection capabilities offered to new connections

Returns:

the capabilities that are offered to new clients on connect.

getConnetionProperties

protected Map<org.apache.qpid.proton.amqp.Symbol,Object> getConnetionProperties()

Load and return a Map that contains the properties that this connection supplies to incoming connections.

Returns:

the properties that are offered to the incoming connection.

getFailedConnetionProperties

protected Map<org.apache.qpid.proton.amqp.Symbol,Object> getFailedConnetionProperties()

Load and return a Map that contains the properties that this connection supplies to incoming connections when the open has failed and the remote should expect a close to follow.

Returns:

the properties that are offered to the incoming connection.

updateTracer

public void updateTracer()

Description copied from interface: AmqpProtocolConverter

On changes to the transport tracing options the Protocol Converter should update its internal state so that the proper AMQP data is logged.

Specified by:

updateTracer in interface AmqpProtocolConverter

keepAlive

public long keepAlive()
               throws IOException

Description copied from interface: AmqpProtocolConverter

Perform any keep alive processing for the connection such as sending empty frames or closing connections due to remote end being inactive for to long.

Specified by:

keepAlive in interface AmqpProtocolConverter

Throws:

IOException - if an error occurs on writing heatbeats to the wire.

getConfiguredReceiverCredit

public int getConfiguredReceiverCredit()

Returns:

the amount of credit assigned to AMQP receiver links created from sender links on the remote peer.

getConfiguredTransformer

public String getConfiguredTransformer()

Returns:

the transformer type that was configured for this AMQP transport.

getConnectionId

public org.apache.activemq.command.ConnectionId getConnectionId()

Returns:

the ActiveMQ ConnectionId that identifies this AMQP Connection.

getClientId

public String getClientId()

Returns:

the Client ID used to create the connection with ActiveMQ

getMaxFrameSize

public long getMaxFrameSize()

Returns:

the configured max frame size allowed for incoming messages.

onAMQPData

public void onAMQPData(Object command)
                throws Exception

Description copied from interface: AmqpProtocolConverter

A new incoming data packet from the remote peer is handed off to the protocol converter for porcessing. The type can vary and be either an AmqpHeader at the handshake phase or a byte buffer containing the next incoming frame data from the remote.

Specified by:

onAMQPData in interface AmqpProtocolConverter

Parameters:

command - the next incoming data object from the remote peer.

Throws:

Exception - if an error occurs processing the incoming data packet.
