public AbstractMessageSplitter()
Method Detail

setApplySequence

public void setApplySequence(boolean applySequence)
Set the applySequence flag to the specified value. Defaults to true.


handleRequestMessage

protected final java.lang.Object handleRequestMessage(Message<?> message)
Description copied from class: AbstractReplyProducingMessageHandler
Subclasses must implement this method to handle the request Message. The return value may be a Message, a MessageBuilder, or any plain Object. The base class will handle the final creation of a reply Message from any of those starting points. If the return value is null, the Message flow will end here.

Specified by:
handleRequestMessage in class AbstractReplyProducingMessageHandler

getComponentType

public java.lang.String getComponentType()
Description copied from class: IntegrationObjectSupport
Subclasses may implement this method to provide component type information.

Specified by:
getComponentType in interface NamedComponent
Overrides:
getComponentType in class AbstractMessageHandler

splitMessage

protected abstract java.lang.Object splitMessage(Message<?> message)
Subclasses must override this method to split the received Message. The return value may be a Collection or Array. The individual elements may be Messages, but it is not necessary. If the elements are not Messages, each will be provided as the payload of a Message. It is also acceptable to return a single Object or Message. In that case, a single reply Message will be produced.
