+
+ senf::console::FlagCollection supplies a special argument type for use in registering
+ console commands. This argument type is used to represent a bit-mask of single flags.
+
+ \code
+ // Function taking a flags argument
+ void func(unsigned flags);
+
+ // Enum containing all the possible flag values
+ enum MyFlags { Foo = 1,
+ Bar = 2,
+ Baz = 4,
+ Doo = 8 };

+
+ // Register the function with a FlagCollection argument type
+ consoleDir.add("func", boost::function<void (FlagCollection<MyFlags>)>(&func));
+ \endcode
+
+ To use the FlagCollection class
+ \li you need a function which takes a bit-mask of flags as argument
+ \li you define and register an enum with all possible flag values
+ \li you register the function with a FlagCollection argument type using \c boost::function
+ for the conversion. This is also possible for return values.
+
+ The nice thing is, that \c boot::function supports compatible argument types and does
+ automatic type conversion. Since a FlagCollection is convertible to and from unsigned long,
+ this conversion will work.
+
+ After registering this function, you can call it with a collection of flags as argument
+
