Interface FunctionN<R>

Type Parameters:

R - the type of the result returned by the function.

All Known Implementing Classes:

DynReflectFunction, FunctionNImpl, StdReflectFunction

public interface FunctionN<R>

Interface that represents a function of an arbitrary number of parameters.

This interface also serves as a bridge between the functions obtained using reflection and the typed functions (Function0..4) used in the rest of the library.
