Method Detail

handleProcessingException

public void handleProcessingException(AdaptrisMessage msg)

Description copied from class: StandardProcessingExceptionHandler

Handles error messages from Workflows by sending them to the configured error producer. The best practice would be for the service to write the message to the filesystem, which is pretty unlikely to fail.

Specified by:

handleProcessingException in interface ProcessingExceptionHandler

Overrides:

handleProcessingException in class StandardProcessingExceptionHandler

Parameters:

msg - the AdaptrisMessage to handle

start

public void start()
           throws CoreException

Description copied from interface: ComponentLifecycle

Starts the component.

Once a component is started it should be ready to process messages. In the case of AdaptrisMessageConsumer, calling start will begin message delivery.

Specified by:

start in interface ComponentLifecycle

Overrides:

start in class StandardProcessingExceptionHandler

Throws:

CoreException - wrapping any underlying Exceptions

stop

public void stop()

Description copied from interface: ComponentLifecycle

Stop the component

A stopped component is not expected to be ready to process messages. In the case of AdaptrisMessageConsumer, calling stop will pause message delivery. Throwing a RuntimeException may cause unintended consequences

Specified by:

stop in interface ComponentLifecycle

Overrides:

stop in class StandardProcessingExceptionHandler

setRetryLimit

public void setRetryLimit(java.lang.Integer i)

Set the limit on the number of retries that a message may have.

Parameters:

i - the number of retries, if less than or equal to 0, then this is considered to be an infinite number of retries.

getRetryLimit

public java.lang.Integer getRetryLimit()

Get the retry limit.

Returns:

the retry limit.

getRetryInterval

public TimeInterval getRetryInterval()

setRetryInterval

public void setRetryInterval(TimeInterval interval)

Set the interval between attempts to retry a failed message.

Parameters:

interval - the interval; default is 10 minutes if not explicitly configured.

failAllMessages

protected void failAllMessages()

failFutureMessages

protected void failFutureMessages(boolean failFuture)

waitingForRetry

protected java.util.Collection<java.lang.String> waitingForRetry()

failMessage

protected void failMessage(java.lang.String s)

failMessage

protected void failMessage(AdaptrisMessage msg)

scheduleNextRun

protected void scheduleNextRun(AdaptrisMessage msg)

filterStarted

protected static java.util.Map<java.lang.String,Workflow> filterStarted(java.util.Map<java.lang.String,Workflow> workflows)
