                                        javax.jbi.messaging.MessageExchange messageExchange)

Description copied from interface: SortingStrategy

Create and return an interceptor chain with the interceptors of the original chain in the order in which they shall be invoked in order to process subsequent message exchanges. The following rules apply for sorting:

• The original interceptor chain must not be modified. Either the unmodified List of interceptors is returned, or a new List with the interceptors in the new order for processing.
• All interceptors from the original inteceptor List are returned, but in the order they shall process message exchanges.

Specified by:

sort in interface SortingStrategy

Parameters:

interceptors - - the interceptor chain to be sorted. This original List will not be modified.

registry - - the interceptor registry containing property data for the interceptors of the chain using the corresponding interceptor instance as key. The properties are merged by Swordfish from the properties returned by the getProperties() method of the interceptor, the property dictionary provided at OSGI service registration, and the Swordfish configuration. Values from the Swordfish configuration have precedence over those provided at OSGI service registration. Hard-coded properties from the getProperties() method have lowest precedence.

Returns:

the filtered interceptor chain (must not be null).
