StatefulChain

class StatefulChain<S, out R>(state: S, seed: S.() -> R, forkState: (S) -> S, gen: suspend S.(R) -> R) : Chain<R>

A chain with possibly mutable state. The state must not be changed outside the chain. Two chins should never share the state.

Parameters

the state of the chain.

forkState

the function to copy current state without modifying it.

fun <S, out R> StatefulChain(state: S, seed: S.() -> R, forkState: (S) -> S, gen: suspend S.(R) -> R)

open suspend override fun collect(collector: FlowCollector<R>)

open suspend override fun fork(): Chain<R>

Create a copy of current chain state. Consuming resulting chain does not affect initial chain.

open suspend override fun next(): R

Generate next value, changing state if needed

fun value(): R?

val gen: suspend S.(R) -> R

var value: R? = null
