Package org.apache.hadoop.hbase.regionserver

Class StoreContext

java.lang.Object

org.apache.hadoop.hbase.regionserver.StoreContext

All Implemented Interfaces:

HeapSize

@Private
public final class StoreContext
extends Object
implements HeapSize

This carries the immutable information and references on some of the meta data about the HStore. This meta data can be used across the HFileWriter/Readers and other HStore consumers without the need of passing around the complete store.
