Output node

Use the Output node as an out terminal for an embedded message flow (a subflow).

This topic contains the following sections:

Purpose

You can use a subflow to provide a common destination for output messages.

You must use an Output node to provide the Out terminal to a subflow; you cannot use a standard output node (a built-in output node such as MQOutput, or a user-defined output node).

You can include one or more Output nodes in a subflow. Each one that you include provides a terminal through which you can propagate messages to subsequent nodes in the message flow in which you include the subflow.

The Output node is contained in the Construction drawer of the palette, and is represented in the workbench by the following icon:

Output node icon

When you select and include a subflow in a message flow, it is represented by the following icon:

Subflow node icon

When you include the subflow in a message flow, this icon exhibits a terminal for each Output node that you included in the subflow, and the name of the terminal (which you can see when you hover over it) matches the name of that instance of the Output node. Give your Output nodes meaningful names, you can easily recognize them when you use their corresponding terminal on the subflow node in your message flow.

Terminals and properties

When you have put an instance of the Output node into a message flow, you can configure it; see Configuring a message flow node. The properties of the node are displayed in the Properties view. To display the properties of the node in the Properties dialog, either double-click the node, or right-click the node and click Properties.

The Output node terminals are described in the following table.

Terminal Description
In The output terminal that defines an out terminal for the subflow.

The following table describes the node properties. The column headed M indicates whether the property is mandatory (marked with an asterisk if you must enter a value when no default is defined); the column headed C indicates whether the property is configurable (you can change the value when you add the message flow to the BAR file to deploy it).

The Output node Description properties are described in the following table.

Property M C Default Description
Node name No No The node type, Output The name of the node.
Short Description No No   A brief description of the node.
Long Description No No   Text that describes the purpose of the node in the message flow.
