Method Detail

of

public static UnalignedFixedWindows of(org.joda.time.Duration size)

perNodeShift

public static long perNodeShift(int nodeId,
                                long windowSize)

windowStartForTimestamp

public static long windowStartForTimestamp(int nodeId,
                                           long windowSize,
                                           long timestamp)

Returns the start of a shifted window that includes the given timestamp. Shifted windows start at: shift + windowNumber(nodeId, windowSize, timestamp) * windowSize,

windowNumber

public static long windowNumber(int nodeId,
                                long windowSize,
                                long timestamp)

Return the number of the shifted window the given timestamp falls into

windowStartForWindowNumber

public static long windowStartForWindowNumber(int nodeId,
                                              long windowSize,
                                              long windowNumber)
