All Implemented Interfaces:

Endpoint, SequenceSender

public class Resequencer
extends ResequencerBase
implements SequenceSender

This pattern implements the Resequencer EIP pattern. The aim of this pattern is to put back into correct order a flow of out-of-sequence messages.

Constructor Detail

Resequencer

public Resequencer()

Method Detail

setCapacity

public void setCapacity(int capacity)

The capacity of this resequencer. The capacity determines the maximum number of message that will be kept in memory to put the messages back in sequence. This determine how far two messages can be in the list of messages while still being put back in sequence.

Parameters:

capacity -

setTimeout

public void setTimeout(long timeout)

Set the timeout of this resequencer. This specifies the maximum number of milliseconds that can elapse between two out-of-sync messages.

Parameters:

timeout -

setComparator

public void setComparator(SequenceElementComparator<javax.jbi.messaging.MessageExchange> comparator)

The comparator used to determine the sequence order of elements.

Parameters:

comparator -

start

public void start()
           throws java.lang.Exception

Specified by:

start in interface Endpoint

Overrides:

start in class EIPEndpoint

Throws:

java.lang.Exception

stop

public void stop()
          throws java.lang.Exception

Specified by:

stop in interface Endpoint

Overrides:

stop in class EIPEndpoint

Throws:

java.lang.Exception

sendSync

public void sendSync(javax.jbi.messaging.MessageExchange exchange)
              throws javax.jbi.messaging.MessagingException

Description copied from interface: SequenceSender

Synchronously sends a single message exchange.

Specified by:

sendSync in interface SequenceSender

Overrides:

sendSync in class SimpleEndpoint

Parameters:

exchange - a message exchange.

Throws:

javax.jbi.messaging.MessagingException - if a system-level error occurs.

sendSync

public void sendSync(java.util.List<javax.jbi.messaging.MessageExchange> exchanges)
              throws javax.jbi.messaging.MessagingException

Description copied from interface: SequenceSender

Synchronously sends a list of message exchanges in the order given by the argument list.

Specified by:

sendSync in interface SequenceSender

Parameters:

exchanges - a list of message exchanges.

Throws:

javax.jbi.messaging.MessagingException - if a system-level error occurs.

processSync

protected void processSync(javax.jbi.messaging.MessageExchange exchange)
                    throws java.lang.Exception

Specified by:

processSync in class EIPEndpoint

Throws:

java.lang.Exception

processAsync

protected void processAsync(javax.jbi.messaging.MessageExchange exchange)
                     throws java.lang.Exception

Specified by:

processAsync in class EIPEndpoint

Throws:

java.lang.Exception
