org.apache.hadoop.hbase.io.hfile
Class HFile.WriterFactory

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.
