[ https://issues.jboss.org/browse/JGRP-1771?page=com.atlassian.jira.plugin.... ] Bela Ban edited comment on JGRP-1771 at 2/10/14 10:57 AM: ---------------------------------------------------------- All relevant methods to read from and write to byte buffers will be defined in org.jgroups.util.Bits, similar to java.nio.Bits. This is only needed for *byte arrays* as *ByteBuffers* already contains methods to do that. h5. Re endian-ness Java uses the big-endian format all the time, and since JGroups does not have to communicate with non-Java processes, we'll ignore endian-ness for the time being. (Note that ByteBuffer does *not* ignore endian-ness). Shift operators ({{<<}} {{>>}}) defined by Java and used in Bits don't simply shift left or right, but they shift towards the MSB ({{<<}}) and LSB ({{>>}}) respectively, so the result is the same in little or big endian systems, and that's why communication between processes on different architectures works in Java. h5. Example The integer 322649 is stored as {{0 4 \-20 89}} on big endian systems and {{89 \-20 4 0}} on little endian systems. However, {{(byte)(322649 >> 8)}} always returns {{\-20}} ({{236}}), regardless of whether it is run on a little- or big endian system. was (Author: belaban): All relevant methods to read from and write to byte buffers will be defined in org.jgroups.util.Bits, similar to java.nio.Bits.
