Constructor Detail

Compound

public Compound(Functor<?> fn1,
                Functor<R> fn2)

Method Detail

getFirstFunctor

public Functor<?> getFirstFunctor()

Returns:

the first of the two nested functors

getSecondFunctor

public Functor<R> getSecondFunctor()

Returns:

the second of the two nested functors

eval

public R eval(java.lang.Object... args)

Description copied from class: Functor

A non-typesafe evaluation method for function objects. The number and types of arguments is not checked at compile time: an invalid number of arguments may cause IndexOutOfBoundsException (or cause extraneous arguments to be ignored); an argument of an invalid type may cause a ClassCastException.

Specified by:

eval in class Functor<R>

accept

public void accept(Visitor v)

Calls the Visitor's visit(Compound) method, if it implements the nested Visitor interface.

Specified by:

accept in interface Visitable

Overrides:

accept in class Functor<R>

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
