Method Detail

recur

public static <V> Trampoline.Continuation<V> recur(Supplier<Trampoline.Continuation<V>> f)

return recur to recur withLast f and a

done

public static <V> Trampoline.Continuation<V> done(V v)

return done to when last value is found

stop

public static <V> Trampoline.Continuation<V> stop()

Return stop when done without a value. Null if on trampoline

seq

                                                 V v)

return seq to yield lazy value v, and continue withLast f a f as null is same as done or stop, depending on v Will behave like recur on a trampoline

trampoline

public static <V> V trampoline(Supplier<Trampoline.Continuation<V>> fun)

Will recur on fun until done(value)

lazy

public static <A,V> Iterable<V> lazy(Supplier<Trampoline.Continuation<V>> fun)

Emits a lazy Iterable recuring until stop, done, null or lack of f
