Abstract Value Members

  1. abstract def elementsRemainingEstimate: Int

    Returns an estimate on the number of remaining elements.

  2. abstract def hasNext: Boolean

  3. abstract def markCompleted(): Boolean

    Attempts to push the stealer to the Completed state.

    Attempts to push the stealer to the Completed state. Only changes the state if the stealer was in the AvailableOrOwned state, otherwise does nothing.

    Note: after having called this operation, the node will either be stolen or completed.

    returns

    true if node ends in the Completed state, false if it ends in the StolenOrExpanded state

  4. abstract def markStolen(): Boolean

    Attempts to push the stealer to the Stolen state.

    Attempts to push the stealer to the Stolen state. Only changes the state if the stealer was in the AvailableOrOwned state, otherwise does nothing.

    Note: after having called this operation, the node will either be stolen or completed.

    returns

    false if node ends in the Completed state, true if it ends in the StolenOrExpanded state

  5. abstract def next(): T

  6. abstract def nextBatch(step: Int): Int

    Commits to processing a block of elements by using next and hasNext.

    Commits to processing a block of elements by using next and hasNext.

    Once hasNext has returned false, nextBatch can be called again.

    step

    approximate number of elements to commit to processing

    returns

    -1 if the stealer is not in the AvailableOrOwned state, otherwise an approximation on the number of elements that calls to next will return.

  7. abstract def split: (Stealer[T], Stealer[T])

    Can only be called on stealers that are in the stolen state.

    Can only be called on stealers that are in the stolen state.

    It will return a pair of stealers traversing the remaining elements of the current stealer.

  8. abstract def state: State

    Stealer state can be AvailableOrOwned, Completed or StolenOrExpanded.

    Stealer state can be AvailableOrOwned, Completed or StolenOrExpanded.

    Stealer state can change from available to either completed or stolen, but cannot change once it is completed or stolen.
