Method Detail

process

public void process(Exchange exchange)
             throws Exception

Description copied from interface: Processor

Processes the message exchange

Specified by:

process in interface Processor

Parameters:

exchange - the message exchange

Throws:

Exception - if an internal processing error has occurred.

process

public boolean process(Exchange exchange,
                       AsyncCallback callback)

Description copied from interface: AsyncProcessor

Processes the message exchange. Similar to Processor.process(org.apache.camel.Exchange), but the caller supports having the exchange asynchronously processed.

If there was a failure processing then the caused Exception would be set on the Exchange.

Specified by:

process in interface AsyncProcessor

Parameters:

exchange - the message exchange

callback - the AsyncCallback will be invoked when the processing of the exchange is completed. If the exchange is completed synchronously, then the callback is also invoked synchronously. The callback should therefore be careful of starting recursive loop.

Returns:

(doneSync) true to continue execute synchronously, false to continue being executed asynchronously

getGroupSize

public Integer getGroupSize()

setGroupSize

public void setGroupSize(Integer groupSize)

getGroupInterval

public Long getGroupInterval()

setGroupInterval

public void setGroupInterval(Long groupInterval)

getGroupDelay

public long getGroupDelay()

setGroupDelay

public void setGroupDelay(long groupDelay)

getGroupActiveOnly

public boolean getGroupActiveOnly()

getNumberFormat

public NumberFormat getNumberFormat()

setNumberFormat

public void setNumberFormat(NumberFormat numberFormat)

getAction

public String getAction()

setAction

public void setAction(String action)

reset

public void reset()

getRate

public double getRate()

getAverage

public double getAverage()

getReceivedCounter

public int getReceivedCounter()

getLastLogMessage

public String getLastLogMessage()

doStart

public void doStart()
             throws Exception

Description copied from class: ServiceSupport

Implementations override this method to support customized start/stop.

Important: See ServiceSupport.doStop() for more details.

Specified by:

doStart in class ServiceSupport

Throws:

Exception

See Also:

ServiceSupport.doStop()

doStop

public void doStop()
            throws Exception

Description copied from class: ServiceSupport

Implementations override this method to support customized start/stop.

Important: Camel will invoke this ServiceSupport.doStop() method when the service is being stopped. This method will also be invoked if the service is still in uninitialized state (eg has not been started). The method is always called to allow the service to do custom logic when the service is being stopped, such as when CamelContext is shutting down.

Specified by:

doStop in class ServiceSupport

Throws:

Exception

See Also:

ServiceSupport.doStart()

createLogMessage

protected String createLogMessage(Exchange exchange,
                                  int receivedCount)

createGroupIntervalLogMessage

protected void createGroupIntervalLogMessage()

messagesPerSecond

protected double messagesPerSecond(long messageCount,
                                   long startTime,
                                   long endTime)
