Exchange Pattern
There are many different Message Exchange Patterns you can use in messaging. This concept is also demonstrated in WSDL and JBI's MEPs.
From there Enterprise Integration Patterns the common examples are
- Request Reply
- Event Message (or one way)
In Camel we have a Pattern enumeration property which is associated with the Message Exchange indicating if a message exchange is a one way Event Message (InOnly) or a Request Reply message exchange (InOut).
