Class BinaryDataInputStream

java.lang.Object
  java.io.InputStream
      org.progeeks.util.BinaryDataInputStream

All Implemented Interfaces:

java.io.Closeable, java.io.DataInput

public class BinaryDataInputStream
extends java.io.InputStream
implements java.io.DataInput

Input stream that will read data in intel byte-ordered format and keep track of exactly how many bytes have been read. WARNING: All DataInput methods return little-endian versions of the shorts/ints/floats that a normal data input would return. This would be a reverse byte ordering when reading a normal file as compared to a regular DatatInput implementation.
