Flow Order mediation primitive

Introduction

You can use the Flow Order mediation primitive to customize the flow by specifying the output terminals to be fired. The Flow Order mediation primitive does not change the input message.

The Flow Order mediation primitive has one input terminal (in) and any number of output terminals. The in terminal is wired to accept a message and the other terminals are wired to propagate a message.

Details

The output terminals are fired in the order that they are defined on the primitive, with each branch completing before the next starts. Each output terminal is fired with an unmodified copy of the input message.

Usage

You can use the Flow Order mediation primitive anywhere that you want to branch a flow. A named output terminal is created for each branch. Each branch of the flow is completed before the next terminal is fired. The only exception to this rule is that if an Asynchronous Service Invoke mediation primitive is reached, the service is called but the Flow Order does not wait for the service invocation to complete before moving on to the next branch. If an exception is thrown by any of the down stream mediation primitives and they do not handle it themselves (for example, via their fail terminal), any remaining flow branches are not fired.
