Class MessagePropertiesContext

java.lang.Object
  org.mule.transport.MessagePropertiesContext

All Implemented Interfaces:

Serializable

public class MessagePropertiesContext
extends Object
implements Serializable

This object maintains a scoped map of properties. This means that certain properties will only be visible under some scopes. The scopes supported by Mule are:

1. PropertyScope.INBOUND Contains properties that were on the message when it was received by Mule. This scope is read-only.
2. PropertyScope.INVOCATION Any properties set on the invocation scope will be available to the current service but will not be attached to any outbound messages.
3. PropertyScope.OUTBOUND Any properties set in this scope will be attached to any outbound messages resulting from this message. This is the default scope.
4. PropertyScope.SESSION Any properties set on this scope will be added to the session. Note that this is a convenience scope in that you cannot directly access session properties from this scope. Session properties can be accessed from the MuleEvent
