+
+== Description ==
+An !ArgumentCompletionList is used to display possible arguments when trying to complete a [wiki:ConsoleCommand] in the [wiki:CommandExecutor] by calling '''complete()'''. !ArgumentCompletionLists are returned by a [wiki:http://www.orxonox.net/wiki/ArgumentCompletionFunctions function] stored in a [wiki:ArgumentCompleter].
+
+An !ArgumentCompletionList is in fact just a std::list with elements that return three strings:
+ * '''getString()''': The string that will be used to complete the command
+ * '''getComparable()''': A string in lowercase used to compare the possible arguments with the already typed argument fragment
+ * '''getDisplay()''': The string that should be displayed in the list (but this is just fake - the other two strings do the real work)
+
+
+== Usage ==
+{{{
+ArgumentCompletionList myList = function();
+std::string fragment = "a";
+
+for (ArgumentCompletionList::iterator it = myList.begin();
+                                      it != myList.end(); ++it)
+{
+    if ((*it).getComparable() starts_with fragment)
+    {
+        std::cout << "Argument: " << (*it).getDisplay() << std::endl;
+        return (*it).getString();
+    }
+}
+}}}
