public class ExpressionMessageSplitter
extends AbstractRoundRobinMessageSplitter

Evaluates a single expression and adds the results of the expression as individual message parts. If you require to execute different expressions for each message part you can use the org.mule.routing.outbound.MultiExpressionMessageSplitter.

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 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
