| /** |
| * <p> |
| * This package contains the interfaces and utilities needed to implement |
| * an aggregation service. |
| * </p> |
| * <p> |
| * Aggregation refers to being able to add data to a data "sink" which |
| * "aggregates" them automatically (e.g. sum them up or average, median etc). |
| * </p> |
| * <p> |
| * An example of an aggregation service is being able to average a series |
| * of <code>int</code> values (perhaps generated from a monitoring component) |
| * and be able to constantly report on the average (or mean) value of |
| * this series. There is no specification about the maximum amount of data that |
| * can be aggregated -- some subclasses might impose such restrictions, |
| * if that is the case then that will be specified in their Javadoc's. |
| * </p> |
