-/**
- * This interface is to be implemented by any broker business object that
- * wishes to gather statistics about messages delivered through it.
- * 
- * These statistics are exposed using a separate JMX Mbean interface, which
- * calls these methods to retrieve the underlying {@link StatisticsCounter}s
- * and return their attributes. This interface gives a standard way for
- * parts of the broker to set up and configure statistics generation.
- * <p>
- * When creating these objects, there should be a parent/child relationship
- * between them, such that the lowest level gatherer can record staticics if
- * enabled, and pass on the notification to the parent object to allow higher
- * level aggregation. When resetting statistics, this works in the opposite
- * direction, with higher level gatherers also resetting all of their children.
