Flexible Architecture

FEAR supports entire architectures, defined as hierarchies of components. A hierarchy is the most generic type of architecture, because both monolithic and flat can be considered a specific subtype.

Each component has access to its children. (This access is called the scope of the component.) FEAR's dynamic C++ framework initializes the components automatically during initialization, so none of the standard code to import interfaces needs to be written manually (as with DirectX).

At the time of writing, all forms of arbitration (independent, suppression, combination, sequence) are supported indirectly; the programmer can implement each as modules in a customized fashion.
