Interface Action

All Known Implementing Classes:

AbstractAction, ForwardAction, ShowMappingsAction

public interface Action

An action is the base of the MAF. Everything that is mapped to a request path must be an action. Actions are singletons (or at least the framework knows only one instance of them).
