Connecting message flow nodes

When you include more than one node in your message flow, you must connect the nodes to indicate how the flow of control passes from input to output. The nodes can be built-in nodes, user-defined nodes, or subflow nodes.

Before you start:

Your message flow might contain just one MQInput node, and one MQOutput node. Or it might involve a large number of nodes, and perhaps embedded message flows, that provide a number of paths that a message can travel through depending on its content.

When you have completed a connection, it is displayed as a black line, and is drawn as close as possible to a straight line between the connected terminals. This might result in the connection passing across other nodes. To avoid this, you can add bend points to the connection.

In the Message flow editor you can display node and connection metadata by hovering the mouse over a node or subflow in a message flow. To view metadata information for a node, subflow or connection:
  1. Open the Broker Application Development Perspective
  2. Open a message flow
  3. In the Editor view, hover the mouse over a node, a subflow, or a node connection in the open message flow by placing the mouse over the element.

If you define a complex message flow, you might have to create a large number of connections. The principle is the same for every connection. You create connections either by using the mouse, or by using the Terminal Selection dialog. See Creating node connections with the mouse and Creating node connections with the Terminal Selection dialog box for more information.

Next: add a bend point.
