Abstract Value Members

  1. abstract def add(value: Long): Unit

    Adds a new datapoint to the histogram.

  2. abstract def clear(): Unit

    Clears all the data from the histogram.

  3. abstract def snapshot(): Snapshot

    Returns an immutable snapshot of the state of the histogram right now.

    Returns an immutable snapshot of the state of the histogram right now.

    If the underlying histogram is latched or buffered, data might be slow to appear or might disappear after some time passes.

    To reread the histogram, snapshot must be called again.
