Examples of org.jgroups.util.Buffer

org.jgroups.util.Buffer
Buffer with an offset and length. Will be replaced with NIO equivalent once JDK 1.4 becomes baseline. This class is immutable. Note that the underlying byte[] buffer must not be changed as long as this Buffer instance is in use ! @author Bela Ban
