The Passthrough node does not process the message in any way. The message that it propagates on its out terminal is the same message that it received on its in terminal.
The Passthrough node is represented in the workbench by the following icon:
Use this node to identify a subflow. For example, if you develop an error processing subflow to include in several message flows, you might want to modify that subflow. However, you might want to introduce the modified version initially to just a subset of the message flows in which it is included. Set a value for the instance of the Passthrough node that identifies which version of the subflow you have included.
When you have put an instance of the Passthrough node into a message flow, you can configure it. Right-click the node in the editor view and click Properties. The node's basic properties are displayed.
All mandatory properties for which you must enter a value (those that do not have a default value defined) are marked with an asterisk on the properties dialog.
Configure the Passthrough node as follows:
Click Cancel to close the dialog and discard all the changes that you have made to the properties.
The Passthrough node terminals are described in the following table.
Terminal | Description |
---|---|
In | The input terminal that accepts a message for processing by the node. |
Out | The input terminal that delivers a message to the subflow. |
The following tables describe the node properties; the column headed M indicates whether the property is mandatory (marked with an asterisk on the properties dialog 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 Passthrough node Basic properties are described in the following table.
Property | M | C | Default | Description |
---|---|---|---|---|
Label | No | No | The label (identifier) of the node. |
The Passthrough node Description properties are described in the following table.
Property | M | C | Default | Description |
---|---|---|---|---|
