Examples of org.switchyard.Exchange

org.switchyard.Exchange
An Exchange represents an instance of a service invocation with a specific message exchange pattern (e.g. InOnly, InOut). Exchange provides a conduit for the messages that flow into and out of a service as part of a service invocation. Unlike messages, an exchange cannot be copied and reused across service invocations. State associated with an invocation (i.e. context) is maintained at the exchange level.
