Subject [jira] Commented: (AMQNET-271) Add support for a Message Transformer to be set in NMS API
Date Mon, 30 Aug 2010 20:25:41 GMT

    [ https://issues.apache.org/activemq/browse/AMQNET-271?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=61529#action_61529

Jim Gomes commented on AMQNET-271:
----------------------------------

Cool.  You can recompile the TIBCO.EMS.cs file and sign it to get rid of that strong name
error.  That .cs file was generated from the original TIBCO.EMS.dll version 4.2 using Doppleganger.

BTW, I checked in the TIBCO changes for this issue.  Feel free to review/correct them.

> Add support in the NMS API for users to set an custom MessageTransformer on the NMS object:

> IConnectionFactory
> IConnection
> ISession
> IMessageProducer
> IMessageConsumer
> The transformer would be an instance of IMessageTransformer which provides two methods:
> {noformat}
>     /// <summary>
>     /// Interface for a class that can Transform a Message from one type to another either
>     /// before consumption or before sent by a producer.
>     /// </summary>
>     public interface IMessageTransformer
>     {
>         /// <summary>
>         /// Called from an IMessageProducer prior to sending the IMessage, allows the
client
>         /// to perform a transformation on the Message prior to it being sent.  This
allows a
>         /// client to configure a single Producer to convert a Message to a format that
can be
>         /// processed by a specific receiving client.
>         /// </summary>
>         IMessage ProducerTransform(ISession session, IMessageProducer producer, IMessage
message);
>         /// <summary>
>         /// Called from an IMessageConsumer prior to dispatching the message to the client
either
>         /// by the 'Receive' methods or from the async listener event.  Allows the client
to perform
>         /// message pre-processing before some messages are dispatched into the client
code.
>         /// </summary>
>         IMessage ConsumerTransform(ISession session, IMessageConsumer producer, IMessage
message);
