StatisticsDisplayFormatter (Apache Accumulo Core 2.1.0-SNAPSHOT API)

java.lang.Object
- org.apache.accumulo.core.util.format.DefaultFormatter
- - org.apache.accumulo.core.util.format.AggregatingFormatter
  - - org.apache.accumulo.core.util.format.StatisticsDisplayFormatter

All Implemented Interfaces:

Iterator<String>, Formatter

public class StatisticsDisplayFormatter
extends AggregatingFormatter
```
Does not show contents from scan, only displays statistics. Beware that this work is being done client side and this was developed as a utility for debugging. If used on large result sets it will likely fail.
