Terminology

• Flow context/Context - just a map with all data needed for processing.
• Data function - is everything matching Function< Map, Map >.
• Action - data function with a name.
• Flow - sequence of actions and a way of their execution and composition. Implements action.
• Selector - extension point, that is responsible for based on context data selection of concrete extension implementation. Implements action.
• Extension - action and configuration map, that helps selector implementation to match this extension. Implements action.
• Feature - responsible for registration of extensions in selectors, stores extension to selector mapping.
• Actor - performs some action upon context with provided data and then deduces result of concrete type T.
• Middleware - named BiFunction< Map< String, Object >, Function< Map, Map >, Function< Map, Map >>, where second argument is data-function to modify, first argument is any kind of meta-data about that data function and return value is modified data-function
• Method converter - converts supplied object into data function
• Data function extracter - extracts method from object as data function
