implements Predicate, Supplier, IntSupplier, LongSupplier, DoubleSupplier, BooleanSupplier, Function, IntFunction, LongFunction, DoubleFunction, UnaryOperator, ToIntFunction, ToLongFunction, ToDoubleFunction, IntUnaryOperator, IntToLongFunction, IntToDoubleFunction, LongUnaryOperator, LongToIntFunction, LongToDoubleFunction, DoubleUnaryOperator, DoubleToIntFunction, DoubleToLongFunction, Consumer, IntConsumer, LongConsumer, DoubleConsumer
```
The classes JxnF, JxnF2, JxnI, JxnL and JxnD together implement all interfaces of package java.util.function for java.util.stream. This allows to explore and use java → aggregate operations interactively from JXN. JxnF implements all single or zero parameter methods, JxnF2 all double parameter methods and JxnI, JxnL and JxnD methods incompatible with Predicate.

- Constructor Detail
  - JxnF
```
public JxnF(JxnFunction f)
```
    Constructs JxnF from an already defined JxnFunction f.
    Can be used, if f is defined using jxn special commands: #function f ... #endfunction
    
    See Also:
    
    JxnF2(JxnFunction)
  - JxnF
```
public JxnF(KmgFormelInterpreter fi,
            String cmd)
```
    Calls constructor JxnFunction( fi, cmd ).
    
    Parameters:
    
    cmd - statement_sequence (one or more statements separated by ';') or #filename[.jxn]. (Note: jxn does not support {…} blocks as possible in java → lambda expressions)

    Description copied from class: JxnFunction
    
    Maps args to $_ and the names passed to the constructor via parameterNames.
    Example:
    fn = @JxnFunction( … ) ! calls a constructor to create a function instance fn
    :
    fn( arg1, arg2, ..., argN ) ! ⇒ jxn internally calls fn.exec( { arg1, arg2, ..., argN } )
