class StdAggregator[T] extends TimeAwareReversibleAggregator[T, Double]

Reversible aggregator that calculates the (biased) standard deviation (e.g. square root of the variance) of the values in the window, weighted by time of validity. It is therefore time-aware and needs entries to be contained in the window.

  4. def addAndDrop(add: TSEntry[T], remove: TSEntry[T]): Unit

    Combine the addition and the removal of entries from the aggregated value.

    Combine the addition and the removal of entries from the aggregated value.

    add

    the entry that will be added at the tail

    remove

    the entry that will be removed at the head

    Combine the addition and the removal of entries from the aggregated value.

    Combine the addition and the removal of entries from the aggregated value.

    add

    the value that will be added

    currentWindow

    the current window, from which we will drop the first entry. Note that it does not yet contain 'add'

  6. def addEntry(entry: TSEntry[T]): Unit

    Update the internal aggregated value according to the entry that is about to be added to the window.

  7. def addEntry(e: TSEntry[T], currentWindow: Queue[TSEntry[T]]): Unit

    Update the internal aggregated value according to the entry that is about to be added to the window.

    Update the internal aggregated value according to the entry that is about to be added to the window.

    e

    the entry that is about to enter the window

    currentWindow

    the current content of the window: it does not include 'e' at this point.

    Definition Classes
    Aggregator
    Note

    By default this ignores the currentWindow and passes the entry to the function that only takes the entry. If you want to use the entire window in the aggregaton you can override this method.

    Updates the aggregated value according to the fact that the head of the currentWindow is being removed.

    currentWindow

    the current content of the window. It still contains the entry that has to be removed
