Interface Fn<IN,OUT>

All Known Subinterfaces:

Fn.AndN<IN,OUT>

All Known Implementing Classes:

EmittingCallbackFn, EmittingCallbackFn.NOP, Fn.Base, Request

public interface Fn<IN,OUT>

Interfaces for functional programming The main interface, Fn, is genericized by an input IN and output OUT. It has 1arg and 2arg methods fn1 and fn2, It accepts an extension interface, Fn.N, if you support a varargs method. For efficiency, two "inner sub-interfaces" are provided

• Fn.Pdouble for dealing with primitive doubles
• Fn.Pint for dealing with primitive ints

"Abstract" Base classes that throw UnsupportedOperationExceptions for all functions are provided for all three types.
