Method Detail

setOutputChannel

public void setOutputChannel(MessageChannel outputChannel)

Description copied from interface: MessageProducer

Specify the MessageChannel to which produced Messages should be sent.

Specified by:

setOutputChannel in interface MessageProducer

Parameters:

outputChannel - The output channel.

setOutputChannelName

public void setOutputChannelName(String outputChannelName)

Set the output channel name; overrides outputChannel if provided.

Parameters:

outputChannelName - the channel name.

Since:

4.3

getOutputChannel

public MessageChannel getOutputChannel()

Description copied from interface: MessageProducer

Return the the output channel.

Specified by:

getOutputChannel in interface MessageProducer

Returns:

the channel.

setErrorChannel

public void setErrorChannel(MessageChannel errorChannel)

setErrorChannelName

public void setErrorChannelName(String errorChannelName)

Set the error channel name. If no error channel is provided, this endpoint will propagate Exceptions to the message-driven source. To completely suppress Exceptions, provide a reference to the "nullChannel" here.

Parameters:

errorChannelName - The error channel bean name.

Since:

4.3

getErrorChannel

public MessageChannel getErrorChannel()

Return the error channel (if provided) to which error messages will be routed.

Returns:

the channel or null.

Since:

4.3

setSendTimeout

public void setSendTimeout(long sendTimeout)

setShouldTrack

public void setShouldTrack(boolean shouldTrack)

Specified by:

setShouldTrack in interface TrackableComponent

getMessagingTemplate

protected MessagingTemplate getMessagingTemplate()

afterSingletonsInstantiated

public void afterSingletonsInstantiated()

Specified by:

afterSingletonsInstantiated in interface SmartInitializingSingleton

onInit

protected void onInit()

Description copied from class: IntegrationObjectSupport

Subclasses may implement this for initialization logic.

Overrides:

onInit in class IntegrationObjectSupport

doStart

protected void doStart()

Takes no action by default. Subclasses may override this if they need lifecycle-managed behavior. Protected by 'lifecycleLock'.

Specified by:

doStart in class AbstractEndpoint

doStop

protected void doStop()

Takes no action by default. Subclasses may override this if they need lifecycle-managed behavior.

Specified by:

doStop in class AbstractEndpoint

sendMessage

protected void sendMessage(Message<?> message)
