initialise

public void initialise()
                throws InitialisationException

Description copied from interface: Initialisable

Method used to perform any initialisation work. If a fatal error occurs during initialisation an InitialisationException should be thrown, causing the Mule instance to shutdown. If the error is recoverable, say by retrying to connect, a RecoverableException should be thrown. There is no guarantee that by throwing a Recoverable exception that the Mule instance will not shut down.

Specified by:

initialise in interface Initialisable

Overrides:

initialise in class AbstractRoundRobinMessageSplitter

Throws:

InitialisationException - if a fatal error occurs causing the Mule instance to shutdown

RecoverableException - if an error occurs that can be recovered from

splitMessage

protected List<Object> splitMessage(MuleMessage message)

Description copied from class: AbstractRoundRobinMessageSplitter

Method used just to split the message into parts. Each part should be an entry in the list. The list can contain either MuleMessage objects or just payloads (Mule will automatically convert the payloads into messages).

This method can be overridden by custom implementations of splitter router where the distribution of the message parts will be done using either round robin or endpoint filtering.

Overrides:

splitMessage in class AbstractRoundRobinMessageSplitter

Parameters:

message - the source message to split into parts

Returns:

a list of payload objects or MuleMessage objects. Usually, it is sufficient just to return payload objects
