ExtendedUUID: add superclass which contains only an int ------------------------------------------------------- Key: JGRP-2077 URL: https://issues.jboss.org/browse/JGRP-2077 Project: JGroups Issue Type: Feature Request Reporter: Bela Ban Assignee: Bela Ban Priority: Minor Fix For: 4.0 ExtendedUUID contains {{flags}} (a short) and arrays of keys and values (byte[] buffers). If someone didn't want the 2 arrays, they'd still pay the cost. Therefore add a subclass of UUID which contains the {{flags}} (an int) field and make ExtendedUUID subclass it and add the arrays. This way, people can choose which one to use.
