Adding a node

When you create a new message flow, the first action to take to define its function is to add nodes.

Before you start

To complete this task, you must have completed one of the following tasks:

To add a node to a message flow:

  1. Switch to the Broker Application Development perspective.
  2. Open the message flow that you want to work with.
  3. Click Selection above the palette of nodes.
  4. Decide which node you want to add. This might be a built-in node or a user-defined node. You can select any of the nodes that appear in the node palette to the left of the editor view. You can only add one node at a time.
  5. In Message Brokers Toolkit Version 5.0, in the palette click the icon that you want to include in the flow and click again in the editor view at the point where you want to add the node.

    In Message Brokers Toolkit Version 5.1, drag-and-drop the node that you want to include in the flow from the node palette into the editor view.

    When you add a node into the editor view, the editor automatically assigns a name to the node. The name is equal to the type of node for the first instance.

  6. Repeat steps 4 and 5 to add further nodes.
  7. You can also add nodes from other flows into this flow. To do this:
    1. Open the other flow, select the node or nodes that you want to copy from the editor or outline views, and press Ctrl+C or click Edit > Copy.
    2. Return to the flow that you are currently working with, and press Ctrl+V or click Edit > Paste. This action copies the node or nodes into your current flow. The node names and properties are preserved in the new copy.

When you have added the nodes that you want in this message flow, you can connect them to specify the flow of control through the message flow, and you can configure their properties.
