Creating parameter instances

Overview

In the “MDAC options” window, the user can access the parameters instantiated by a given MDA component, and define options for it.

To create a parameter instance, you must first create a profile parameter in a J profile implementation.

Parameters are defined in the groups in which they appear.

Note: Profile parameters that are not instanciated by an MDA component do not appear in the “MDAC options” window and cannot be modified.

Creating a group

Groups can be instantiated by clicking on the icon from a J MDA component.

Steps:

1. In the explorer, select the J MDA component whose parameters you wish to instantiate.

2. Click on the and confirm by clicking on “OK”. The “Group” dialog box then appears.

3. Enter a name for your new parameter group and click on “OK” to confirm.

Creating a parameter instance

Profile parameters can be instantiated by clicking on the icon from a group of a J MDA component.

Steps:

1. In the explorer, select the new parameter group.

2. Click on the icon. The “Parameter instance” window then appears.

3. In the window, enter a name for the new parameter instance and define the parameter it will instantiate, and then click on “OK” to confirm.

After carrying out these operations and compiling the J MDA component, the parameter appears in the “MDAC options” window (Figure 163).

Toolbar

The icons appearing in the “MDA” tab of the auxiliary window can be used to run the following commands:
