edu.harvard.hul.ois.jhove.module.jpeg2000.FragmentInputStream
- All Implemented Interfaces: 
- java.io.Closeable
- public class FragmentInputStream 
- extends java.io.InputStream
A FragmentInputStream provides an interface by which
 the scattered fragments of a Fragment List Box can
 be read as a single stream.  Only fragments within
 the originating file are supported, not fragments
 in external files.
