HFile.WriterFactory (Apache HBase 1.4.11 API)

java.lang.Object
- org.apache.hadoop.hbase.io.hfile.HFile.WriterFactory

Enclosing class:

HFile
```
public abstract static class HFile.WriterFactory
extends Object
```
This variety of ways to construct writers is used throughout the code, and we want to be able to swap writer implementations.
