How to Add Nil Value Functoids to a Map

The Nil Value functoid sets the value of the destination node to Nil.

For conceptual information about the Nil Value functoid, see Nil Value Functoid.

Add the Nil Value functoid to a map and configure it

With the Visual Studio Toolbox active, click the Advanced Functoids tab to select that category of functoids. The list of advanced functoids in the chosen category appears.
Drag the Nil Value functoid () from the Toolbox to the appropriate location on a grid page.

Note

The functoid will be placed on the displayed grid page. If you want to put the functoid onto a different grid page, you need to display that other grid page first.

If you are constructing a map that uses more than one functoid, you need to consider their relative left-to-right placement. Functoids are executed from left to right. The output of a functoid can only be input to another functoid that is farther to the right.
The Nil Value functoid can have zero to one input parameters. If there is no input parameter for this functoid, the target node is set to Nil. To establish the input parameter for the Nil Value functoid, create an input link by dragging the output from some other Logical functoid or from a variable Boolean field in the input instance message.
To use the output parameter from the Nil Value functoid, create an output link by dragging the Nil Value functoid to a record or field in the destination schema.

Note

As with other functoids, the output of the Nil Value functoid can be used as input to another functoid.
