AbstractOperationStatistic (Terracotta Statistics 2.1 API)

java.lang.Object
- org.terracotta.statistics.AbstractSourceStatistic<ChainedOperationObserver<? super T>>
- - org.terracotta.statistics.AbstractOperationStatistic<T>

All Implemented Interfaces:

OperationObserver<T>, OperationStatistic<T>, SourceStatistic<ChainedOperationObserver<? super T>>
```
public abstract class AbstractOperationStatistic<T extends Enum<T>>
extends AbstractSourceStatistic<ChainedOperationObserver<? super T>>
implements OperationStatistic<T>
```

Implementation Note:

begin() and end(Enum) must be called from the same thread so that latency can be computed.
