Capgemini MeSH - Messaging Framework
• Abstracts away WSE or WCF
• Simple interface
• Chained together
• Composable at Deploy Time (.config)
• Top of the 'CDAF Stack' for Services
Capgemini MeSH – Chain of Responsibility
• Implemented with the 'Chain of Responsibility' pattern
• Definition (GoF) –• 'Avoid coupling the sender of a request to its receiver by giving
more than one object a chance to handle the request. Chain the receiving objects and pass the request along the chain until an object handles it.'
Client Handler
ConcreteHandlerA ConcreteHandlerB successor
Capgemini MeSH – Pipes and Filters
• Based on the Pipes and Filters pattern• See 'Enterprise Integration Patterns'
• By Gregor Hohpe & Bobby Woolf - Addison Wesley
• Definition –• 'Use the Pipes and Filters architectural style to divide a larger
processing task into a sequence of smaller, independent processing steps (Filters) that are connected by channels (Pipes).'
