Class FormalArgument

java.lang.Object
  org.antlr.stringtemplate.language.FormalArgument

public class FormalArgument
extends java.lang.Object

Represents the name of a formal argument defined in a template: group test; test(a,b) : "$a$ $b$" t() : "blort" Each template has a set of these formal arguments or uses a placeholder object: UNKNOWN (indicating that no arguments were specified such as when a template is loaded from a file.st). Note: originally, I tracked cardinality as well as the name of an attribute. I'm leaving the code here as I suspect something may come of it later. Currently, though, cardinality is not used.
