| /** |
| * <p>This package is dedicated to streaming algorithms that enable estimation of the |
| * frequency of occurence of items in a weighted multiset stream of items. |
| * If the frequency distribution of items is sufficiently skewed, these algorithms are very |
| * useful in identifying the "Heavy Hitters" that occured most frequently in the stream. |
| * The accuracy of the estimation of the frequency of an item has well understood error |
| * bounds that can be returned by the sketch.</p> |
| * |
| * <p>These sketches are mergable and can be serialized and deserialized to/from a compact |
| * form.</p> |
