Template Modules

A Template Module is a Module that contains TemplateInput and TemplateOutput Attributes that contain, respectively a variable specifying the input and output of the Module. This lets you treat the module node much like a variable.

Suppose Module M contains variable Y in its TemplateOutput. When you move your mouse cursor over the node M, it shows a result icon. Click the result icon to see the value of M, which is actually the value of Y. When you draw an arrow from M to another variable or module, it acts as if you are drawing an arrow from Y. It lets you enter Y<\code> into the Definition of the destination node.

Similarly, suppose module M contains variable X in its TemplateInput. Drawing an arrow from another variable or module A into the node for M is equivalent to drawing an arrow into X. If the definition of X contains a list in square bracket [], ListOfHandles, Edit table or a function with Repeated parameters, it automatically adds A into the definition of X, as described in Model building by mouse.

If you define a Template Module with a TemplateInput containing a variable with one of these kinds of definition and TemplateOutput, you can create a model by making copies of the template, and linking them together simply by drawing arrows. In this way, you can create a class of Analytica models that are extremely easy to construct and extend simply by copying modules and linking them together. See Model building by mouse for more.
