A Method node (
) represents a method — a small program that runs when called from other nodes, such as
Event nodes,
Item nodes,
Buttons nodes, and other
Method nodes. The name of the
Method node is the name of the method, which you can enter in the
Name field. Right-click and choose
Edit (
) to open an editor window where you can edit the method. For local methods, click the
Go to Source button (
) to move to the form object from which the local methods is created. See
Creating Methods and
The Method Nodes and Method Editor Windows for information about creating methods and
Debugging and Running Methods for Applications for information about the debugging tools.
Methods can also be used to run code in connection with a model defined in the Model Builder window. The
Show in Model Builder check box is selected by default. The method then appears in the
Run Method list in the
Developer ribbon.
The Settings window for a
Method node contains the following section.
In the table under Inputs, you can add one or more inputs to the method. Click the
Add button (
) to add an argument to the list.
In the Name column, you can edit the name of the argument (default:
arg1, and so on). In the
Type column, choose a data type (
String,
Boolean,
Integer,
Double, or a 1D or 2D array type). You can assign a default value in the
Default column; the syntax is the same as for declarations (see
Array Syntax). You can also enter a description of the input in the
Description column. The descriptions can be used to annotate the method parameters and as a label for inputs in
Method Call features.
For method inputs of the double types, there is an optional unit definition that you define in the Unit column The unit definition is used by
Method Call features to append a label to the input text field and to convert values to the desired unit when running the method call.
Use the Move Up (
),
Move Down (
), and
Delete (
) toolbar buttons to organize and remove commands from the list.
From the Output list, select an output data type:
None (the default, for no output);
String;
Boolean;
Integer;
Double; or a 1D or 2D array type. For all output data types, you can enter a name for the method’s output in the
Name field (default:
out). The value of the output variable is what the method returns. If it is unassigned, the method returns the default value for the type (0,
null, or
false).
