Class DefaultMuleEvent

java.lang.Object

org.mule.DefaultMuleEvent

All Implemented Interfaces:

Serializable, MuleEvent, ThreadSafeAccess, DeserializationPostInitialisable

public class DefaultMuleEvent
extends Object
implements MuleEvent, ThreadSafeAccess, DeserializationPostInitialisable

DefaultMuleEvent represents any data event occurring in the Mule environment. All data sent or received within the Mule environment will be passed between components as an MuleEvent.

The MuleEvent holds some data and provides helper methods for obtaining the data in a format that the receiving Mule component understands. The event can also maintain any number of flowVariables that can be set and retrieved by Mule components.

Method Detail

resolveEventSynchronicity

protected boolean resolveEventSynchronicity()

fillProperties

protected void fillProperties(InboundEndpoint endpoint)

ignoreProperty

protected boolean ignoreProperty(String key)

This method is used to determine if a property on the previous event should be ignored for the next event. This method is here because we don't have proper scoped handling of meta data yet The rules are

1. If a property is already set on the current event don't overwrite with the previous event value
2. If the property name appears in the ignoredPropertyOverrides list, then we always set it on the new event

Parameters:

key - The name of the property to ignore

Returns:

true if the property should be ignored, false otherwise

extractCredentials

protected Credentials extractCredentials(InboundEndpoint endpoint)

getCredentials

public Credentials getCredentials()

Specified by:

getCredentials in interface MuleEvent

public MuleMessage getMessage()

Description copied from interface: MuleEvent

Returns the message payload for this event

Specified by:

setStopFurtherProcessing

public void setStopFurtherProcessing(boolean stopFurtherProcessing)

Setting this parameter will stop the Mule framework from processing this event in the standard way. This allow for client code to override default behaviour. The common reasons for doing this are - 1. The service has more than one send endpoint configured; the service must dispatch to other prviders programmatically by using the service on the current event 2. The service doesn't send the current event out through a endpoint. i.e. the processing of the event stops in the uMO.

Specified by:

setStopFurtherProcessing in interface MuleEvent

Parameters:

stopFurtherProcessing - The stopFurtherProcessing to set.
