      extended byjava.io.ByteArrayInputStream
          extended byorg.apache.jdo.impl.fostore.FOStoreInput
All Implemented Interfaces:
java.io.DataInput

class FOStoreInput
extends java.io.ByteArrayInputStream
implements java.io.DataInput

Extend ByteArrayInputStream so that we can get ahold of the byte array and current position, and can change the current position.
