Interface LazyFunction<T>


public interface LazyFunction<T>
A lazy function is used to populate a Flow incrementally. Lazy functions allow calculations to be deferred. They also support infinitely large Flows, where successive values are computed just as needed.

    Calculates the next value for the function.
  • Method Details

    • next

      Calculates the next value for the function. The return value is tricky: it combines the next value in the Flow with a function to compute the value after that as a LazyContinuation. Alternately, a LazyFunction can return null to indicate that it has returned all the values it can.
      Returns:
      continuation containing next value and next function, or null when no more values can be produced
