| Event summary |
| Fn | Provides functional operations on EPL containers, such as map, reduce, filter and slice. |
| Functional | Wrapper event for usage of Fn in a fluent style. Contains instance methods for operators, static methods for creation, all of which return values wrapped in a Functional for further calls. Functors and predicates are still used from Fn. The underlying value can be retrieved at the end of the chain with the get action. |
| Generator | Represents a generator over a function. This class is used internally by Functional, but you can use any event with a generate method. Generate methods must take 0 arguments and can return the type of your choice (or any). |
| Partial | A partially evaluated function which can be passed to functional operators or later executed with the remaining arguments. |
