AbstractHistogramBase

java.lang.Object
- org.HdrHistogram.EncodableHistogram
- - org.HdrHistogram.AbstractHistogramBase

Direct Known Subclasses:

AbstractHistogram
```
abstract class AbstractHistogramBase
extends EncodableHistogram
```
This non-public AbstractHistogramBase super-class separation is meant to bunch "cold" fields separately from "hot" fields, in an attempt to force the JVM to place the (hot) fields commonly used in the value recording code paths close together. Subclass boundaries tend to be strongly control memory layout decisions in most practical JVM implementations, making this an effective method for control filed grouping layout.
