Class LEDataInputStream

java.lang.Object
  gov.nist.microanalysis.EPQTools.LEDataInputStream

All Implemented Interfaces:

java.io.DataInput

public class LEDataInputStream
extends java.lang.Object
implements java.io.DataInput

Very similar to DataInputStream except it reads little-endian instead of big-endian binary data. We can't extend DataInputStream directly since it has only final methods. This forces us implement LEDataInputStream with a DataInputStream object, and use wrapper methods.
