replace `ResourceIterator` with `AutoCloseableSequence` ? #2

Closed sszuev closed 1 year ago

sszuev commented 1 year ago

Example: 

class AutoCloseableSequenceImpl<X>(private val source: Iterator<X>): Sequence<X>, AutoCloseable {
    override fun iterator(): Iterator<X> = source

    override fun close() {
        TODO("Not yet implemented")
    }
}

fun <T, R> AutoCloseableSequenceImpl<T>.map(transform: (T) -> R): AutoCloseableSequenceImpl<R> {
    val theSequence = this as Sequence<T>
    return AutoCloseableSequenceImpl(theSequence.map(transform).iterator())
}

We can't control every method of Sequence. No worth to do.

ResourceIterator is now a separated lib: https://github.com/DataFabricRus/resource-iterator
