| Method Summary | |
| public void | accept(Visitor v)
No-op implementation of Visitable interface. | | public Generator<R> | bind(T val)
FactoryMethod that binds the argument arguments to this function to a specific
value. | | public UnaryFunctor<F, R> | compose(UnaryFunctor<F, T> f)
FactoryMethod that creates a UnaryFunctor that passes its argument to
the given functor, and uses the result as the argument to this
function. | | public BinaryFunctor<F1, F2, R> | compose(BinaryFunctor<F1, F2, T> f)
FactoryMethod that creates a BinaryFunctor that passes its arguments to
the given functor, and uses the result as the argument to this
function. | | public R | eval(Object... args)
Executes the function and returns the result. | | abstract public R | fn(T arg)
Executes the function and returns the result. | | public Generator<R> | generate(Generator<T> gen)
FactoryMethod that creates a Generator to create the argument to this
function. |
| accept | | public void accept(Visitor v)(Code) | | No-op implementation of Visitable interface.
|
| bind | | public Generator<R> bind(T val)(Code) | | FactoryMethod that binds the argument arguments to this function to a specific
value. The new functor will return
fnthis(val).
|
| compose | | public UnaryFunctor<F, R> compose(UnaryFunctor<F, T> f)(Code) | | FactoryMethod that creates a UnaryFunctor that passes its argument to
the given functor, and uses the result as the argument to this
function. Given argument x, the new functor will return
fnthis(f(x)))
|
| compose | | public BinaryFunctor<F1, F2, R> compose(BinaryFunctor<F1, F2, T> f)(Code) | | FactoryMethod that creates a BinaryFunctor that passes its arguments to
the given functor, and uses the result as the argument to this
function. Given arguments x and y, the new functor will
return fnthis(f(x,y)))
|
| eval | | public R eval(Object... args)(Code) | | Executes the function and returns the result.
|
| fn | | abstract public R fn(T arg)(Code) | | Executes the function and returns the result.
|
| generate | | public Generator<R> generate(Generator<T> gen)(Code) | | FactoryMethod that creates a Generator to create the argument to this
function. The new functor will return
fnthis(gen()).
