Interface IFunctionN

public interface IFunctionN

Interface to be implemented to define a function that accepts N parameters in the form of an array of Objects and that returns an Object as a result.

It is not necessary to implement this interface in order to use functions. Subclasses of ReflectionFunction can be used to construct Function objects using reflection. However, if you do not want to use reflection (for performance reasons, more compile-time validation, easier refactoring, or any other reason), using this interface and the FunctionN class gives* you an alternative.
