Class ByteArray

java.lang.Object

org.knopflerfish.util.ByteArray

public class ByteArray
extends java.lang.Object

A converter class used to read primitive datatypes from, or write them to, a bytearray, starting at position index. The data is stored as big-endian in the array (the most significant value in the sequence is stored first at the lowest storage address).
