net.sourceforge.stripes.config.Configuration

Type safe interface for accessing configuration information used to configure Stripes. All Configuration implementations are handed a reference to the BootstrapPropertyResolver to enable them to find initial values and fully initialize themselves. Through the BootstrapPropertyResolver implementations also get access to the ServletConfig of the DispatcherServlet which can be used for locating configuration values if desired.

Implementations of Configuration should fail fast. At initialization time they should detect as many failures as possible and raise an exception. Since exceptions in Configuration are considered fatal there are no exception specifications and implementations are expected to throw runtime exceptions with plenty of details about the failure and its suspected cause(s).
