Constructor Detail

TimerEndpoint

public TimerEndpoint()

TimerEndpoint

public TimerEndpoint(String uri,
             Component component,
             String timerName)

TimerEndpoint

protected TimerEndpoint(String endpointUri,
             Component component)

Method Detail

getComponent

public TimerComponent getComponent()

Description copied from class: DefaultEndpoint

Returns the component that created this endpoint.

Overrides:

getComponent in class DefaultEndpoint

Returns:

the component that created this endpoint, or null if none set

createProducer

public Producer createProducer()
                        throws Exception

Description copied from interface: Endpoint

Creates a new producer which is used send messages into the endpoint

Specified by:

createProducer in interface Endpoint

Returns:

a newly created producer

Throws:

Exception - can be thrown

createConsumer

public Consumer createConsumer(Processor processor)
                        throws Exception

Description copied from interface: Endpoint

Creates a new Event Driven Consumer which consumes messages from the endpoint using the given processor

Specified by:

createConsumer in interface Endpoint

Parameters:

processor - the given processor

Returns:

a newly created consumer

Throws:

Exception - can be thrown

isSingleton

public boolean isSingleton()

Description copied from interface: IsSingleton

Whether this class supports being singleton or not.

Specified by:

isSingleton in interface IsSingleton

Returns:

true to be a single shared instance, false to create new instances.

doStart

protected 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.

Overrides:

doStart in class DefaultEndpoint

Throws:

Exception

See Also:

ServiceSupport.doStop()

doStop

protected 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.

Overrides:

doStop in class DefaultEndpoint

Throws:

Exception

See Also:

ServiceSupport.doStart()

isMultipleConsumersSupported

@ManagedAttribute
public boolean isMultipleConsumersSupported()

Description copied from interface: MultipleConsumersSupport

Are multiple consumers supported?

Specified by:

isMultipleConsumersSupported in interface MultipleConsumersSupport

Returns:

true if multiple consumers are supported

getTimerName

@ManagedAttribute(description="Timer Name")
public String getTimerName()

setTimerName

@ManagedAttribute(description="Timer Name")
public void setTimerName(String timerName)

The name of the timer

isDaemon

@ManagedAttribute(description="Timer Daemon")
public boolean isDaemon()

setDaemon

@ManagedAttribute(description="Timer Daemon")
public void setDaemon(boolean daemon)

Specifies whether or not the thread associated with the timer endpoint runs as a daemon.

The default value is true.

getDelay

@ManagedAttribute(description="Timer Delay")
public long getDelay()

setDelay

@ManagedAttribute(description="Timer Delay")
public void setDelay(long delay)

The number of milliseconds to wait before the first event is generated. Should not be used in conjunction with the time option.

The default value is 1000.

isFixedRate

@ManagedAttribute(description="Timer FixedRate")
public boolean isFixedRate()

setFixedRate

@ManagedAttribute(description="Timer FixedRate")
public void setFixedRate(boolean fixedRate)

Events take place at approximately regular intervals, separated by the specified period.

getPeriod

@ManagedAttribute(description="Timer Period")
public long getPeriod()

setPeriod

@ManagedAttribute(description="Timer Period")
public void setPeriod(long period)

If greater than 0, generate periodic events every period milliseconds.

The default value is 1000.

getRepeatCount

@ManagedAttribute(description="Repeat Count")
public long getRepeatCount()

setRepeatCount

@ManagedAttribute(description="Repeat Count")
public void setRepeatCount(long repeatCount)

Specifies a maximum limit of number of fires. So if you set it to 1, the timer will only fire once. If you set it to 5, it will only fire five times. A value of zero or negative means fire forever.

getTime

public Date getTime()

setTime

public void setTime(Date time)

A java.util.Date the first event should be generated. If using the URI, the pattern expected is: yyyy-MM-dd HH:mm:ss or yyyy-MM-dd'T'HH:mm:ss.

getPattern

public String getPattern()

setPattern

public void setPattern(String pattern)

Allows you to specify a custom Date pattern to use for setting the time option using URI syntax.

getTimer

public Timer getTimer(TimerConsumer consumer)

setTimer

public void setTimer(Timer timer)

To use a custom Timer

removeTimer

public void removeTimer(TimerConsumer consumer)
