Type

Application item

Available from

Return Node only

Purpose

When using a modular approach to application design, it is often necessary to pass variable or constant values from one module to another. With Output Parameter item, a speech project used as a module node can pass data back to the parent speech project.

For more information about creating and using application modules, see Module Nodes.

Behavior

Use the Output Parameter item when you want to pass a variable value from a module node to the parent speech project. To pass values from the module back to the parent application, you must place one Output Parameter item into the Return node for each value that you want to pass back.

Once you generate and save your module, you must deploy it as a Dialog Designer module. For more information on the procedure to deploy Dialog Designer modules, see Deploying Projects as Dialog Designer Modules.

When you use your speech project as a module in another project, Dialog Designer automatically populates the module node with one Module Output item for each Output Parameter item in the module. For more information, see Module Output.

Properties

• Name - Enter a name for the Output Parameter item.

• Dialog Designer automatically assigns a default name when you place the Output Parameter item in the node. You can use the default name or rename it.

• Description - (Optional) Enter a brief description of what the output parameter value is used for. Avaya recommends you to write a good description so that when you use the module in another speech project, you can find out what the output parameter is used for.

• Variable - Select the variable whose value you want to pass back to the parent application. If the variable you select is a complex variable, you must also select a Variable Field.

• Variable Field - If you have selected a complex variable in the Variable field, you must select the field whose value you want to pass back to the parent application from the drop-down list. If you have selected a simple variable in the Variable field, this field is blank.

• Expression - Enter the ECMAscript expression you want to pass to the object.
